May I check i have been combing through the new dji a3 controller specs and seen that for the rtk gps they are using dual antennas as a redundant compass by using the different positions of each gps antenna to calculate what direction the vehicle is The GPS system may consist of dual or a single module, but two antennas are required in each case. kalai1219 (Kalai1219) December 5, 2022, 7:42am 1. Please checks my parameter. Like multiple Radiolink SE100 or something. Hallo! Bought a set of mRo. Yes, GPS 1 Specifically. now I know that this question can be out of topic, but I’m very interested in understanding the math which is behind the calculation for the heading and the motor commands used by ArduPilot Rover. the other, perfect, 30 or more sats. When we first start up our copter and ground station it says we have two GPS’s. If you're working with a flight controller and GNSS module combination that does not comply with the Pixhawk connector standard then you will need to pay particular attention to the connector I have been working on a robot mower and tried the LC29 RTK GPS with results that were just kinda OK. Maybe setting type 22 and type 23 for As the new uBlox Zed-F9P GPS is starting to become available I thought it would be worthwhile to do some side by side testing with the previous generation uBlox M8P. Dual unit Serial GPS modules must be connected to ArduPilot via their (not the autopilots’s) UART1 connectors, DroneCAN modules via I want to use Dual GPS HERE2 with Cune Orange pixhawk. When I unplug the second GPS unit so that there is only one on the CAN bus, it works just fine. I have a Pixhawk (from 3DR) and I know both it and AC support dual GPS, but I can’t seem to find any explanation as to whether the two units must be identical in order to work correctly (to be specific, I have two Neo-M8N GPS units from different manufacturers and while they share the same u-blox modules I suspect they have different compasses. When I tested now with stable rtk-fix, and turned off the magnetometer, it was clear to see that the pixhawk had a stable heading when the gps was connected, and started to drift when I disconneted it. Hardware. I have the GPS module (K726 from sinoGNSS) output NMEA which I have already checked with terminal software via UART, at 10Hz. In fact, the Compass value in EKF is very unstable during flight. I set GPS_TYPE = 9, and GPS_TYPE2 = 1 (auto). instance2 to use GPS. The setup as described in the arducopter wiki which also makes use of 2 x F9p Gps unit: ArduPilot Discourse Dual Here4 gps issues on same can port (can2) ArduCopter. Can you confirm which module is which and that they are correctly [image] ArduPilot has supported Dual GPS for quite some time but it has always only been using one or the other GPS (whichever had higher number of satellites). Can someone just confirm And when i use dual gps, can the data from two gps can appear seperately ? GPS naming / ordering question Jai. So I modified the parameters to the best of my knowledge. If I understand correctly, in order to calculate the correct heading, ardurover uses a EKF instance for each IMU installed on the pixhawk, so, in total 3 EKF instances for the IMUs and another EKF for the GPS yaw calculated by using the coordinates coming from the two GPS modules mounted on the rover. Current draw is also lower overall than the other vehicle shows (the first hovers at ~80A, where this one is ~65A). Using two GPSes reduces the chance of glitches affecting the vehicle. Hi All. Should i use CAN 1 and CAN 2, or CAN 1 and GPS1, or a CAN splitter on CAN 1 only? As far as I know ardupilot doesn’t support dual CAN GPS yet, so you need 1 GPS in CAN mode and another in I2C mode. In particular, I’m very curious to understand how and if the Kalman filter is used when, for example, the compass is disabled and only two GPS modules are used to calculate Having just added a second GPS (M8N) to my Taro680PRO, I seem to be receiving nearly continuous GPS-2 glitch errors. We have the M8N GPS/compass module feeding into SERIAL3 and our own RTK GPS solution feeding NMEA messages to SERIAL4. One option was taking a NMEA heading sentence from a dual antenna Hemisphere unit. It supports multiple GNSS options such as BeiDou, Galileo, GLONASS, GPS, QZSS. gps, rtkgps, auto, dual-gps-setup, autopilot. dual_gps 1920×963 174 KB. in the can2, we have connected both gps and power by external Hello there. There is no external safety switch. As soon as I connect the USB for the base station RTK and click connect. 4, we encountered problems with the SBF dual antenna configuration. Apparently The following parameter instructions assume Serial3 and Serial4 are used for serial connecting GPSes but any serial port(s) should work as long as the first port using protocol 5 is connected to one of the GPS. i have been combing through the new dji a3 controller specs and seen that for the rtk gps they are using dual antennas as a redundant compass by using the different positions of each gps antenna to calculate what direction the vehicle is pointing. Will be interesting to compare GPS data against attitude and current on this second vehicle as your tests increase in intensity. param (17. Thanks. Mission planner defines as 3 compass. 5.

GAY (Jai GAY) May 30, 2024, 1:08am There is no problem using a second GPS on Pixhawk but you cannot add an extra compass. The first GPS’s data appears with an instance number of 0 in the GPS and GPA messages. I’ve built several rigs with original Pixhawk and Cube FCs, but this is my first time using a CAN GPS, a Here3. I think Ardupilot does allow NMEA and UBX at the same time because you can set GPS_TYPE and GPS_TYPE2 different to be NMEA or UBX. However, the message “Bad GPS Signal Health” is displayed. The EKF character in the Hud window Auto mode depends on the GPS’s self-reporting status. This testing is without external corrections, so both The following parameter instructions assume Serial3 and Serial4 are used for serial connecting GPSes but any serial port(s) should work as long as the first port using protocol 5 is connected to one of the GPS. Multiple GPS and/or Compasses can be used in the system, see GPS Blending (aka Dual GPS), Advanced Compass Setup, and EKF3 Affinity and Lane Switching for more information. 42 MHz) and optionally they can receive SBAS DGPS corrections giving meter precision.

In the attached document, I have described the problem in ArduPilot bends the two GPS to improve location, but does not calculate a heading. Should I use one driver and have both interfaces CAN1/CAN2 using this driver? Or would it be recommended to use one driver for each GPS unit? What are the pros and cons with Hi all, I have two GPS receivers and was wondering if Arducopter can get the heading information from the spatial difference of the receivers instead of using the compass. Copter 4. drive. Recently I procured two Here3+ GPS units. One would be GPS1 that is HERE 3 and other is GPS2(Not HERE GPS). Hello, I have trying connecting dual gps on pixhawk cube. You cannot use the compass, on the added GPS unit, as it will give address conflict on the I2C-bus if you don’t have a device where you can set the I2C address. 26478. I went into Full Params and enabled the 2nd GPS [GPS_TYPE_2 = 1] but nowhere in mission planner does it seem to Hi all, We just installed CUAV F9P RTK on our copter and ground station. ArduPilot Discourse Using Multi GPS. one of them, gp1 always with gps bad fix issues. I splurged a bit and bought the Dual antenna Holybro H-RTK Mosaic-H GPS system for GPS YAW only to find little in the way of documentation on this new system. The receiver is capable of concurrently tracking global civil navigation systems, including GPS, GLONASS, GALILEO, BEIDOU and QZSS. And they are directed in different directions. Dual unit Serial GPS modules must be connected to ArduPilot via their (not the autopilots’s) UART1 connectors, DroneCAN modules via I have 2 identical F9P GPS module working as dual GPS for AC4. This LED is supported in PX4 ArduPilot Discourse Dual airspeed sensor problem. gps, rtk, gnss, hereplus. Hello, We are wondering what happens if we have both a Here RTK and a normal Here 2 non-RTK GNSS receivers onboard, running Copter firmware. #1-11 minutes! #2-40 sec. I would have a question as regards the working of GPS The first GPS’s data appears with an instance number of 0 in the GPS and GPA messages. When i plug in the radar altimeter the setup stops working. Jim Also tried the latest 1. Setup: Arducopter 3. 5-rc11 dual gps issues. 32 with a arduplane piwhawk 1. Keep a distance between them. NTF_LED_TYPES: 231 Set to DRONECAN for LED type. ArduPilot and DroneCAN provide a means to Dual DroneCAN GPS. Thing I want to do: I want to use dual GPS’. I used exactly the same configuration that I used for Here3 GPS. i have updated the both here4 firmware by mission planner to latest 1. Yesterday, I had a first test-flight using the “GPS for Yaw” feature of ArduCopter 4. 1 (copter 3. ardu 4. The blended GPS data appears with an instance number of 2 in the GPS and GPA messages. I only have one Here3 hooked up. I know that ArduPilot kalman-filters multiple GPS’ position data. The GPS system may consist of dual or a single module, but two antennas are required in each case” This is common practice with ArduPilot, but it is not strictly required just to get a GPS-based heading solution. For dual unit systems, the 1st GPS and 2nd GPS should be Only 2 GPS modules are fully supported. GPS for Yaw (aka Moving Baseline) GPS for Altitude; GPS/Non-GPS Transitions; It is possible to use multiple radio control receivers in ArduPilot for redundancy or hand-off between multiple transmitters. See also here GPS Blending (aka Dual GPS) — Plane documentation (ardupilot. I built an arduino based RC mower last year and recently wanted to Here 4 is a professional High Precision Dual-band RTK Navigation module. Can I just connect the second AS to the same I2C? As I use also Dual Gps, is it a problem? Anybody can help me how to setup the parameter in Mission Planner? Another question is how the Pixhawk 1 will treat the second AS? Is there any option Vehicle: normal setup for serial GPS (GPS1_TYPE = 1) or DroneCAN GPS (GPS1_TYPE = 9) Attach RTK GPS via USB to PC running Mission Planner or QGC. Set BRD_SAFETYENABLE as 0 to disable safety switch, or connect an physical The following parameter instructions assume Serial3 and Serial4 are used for serial connecting GPSes but any serial port(s) should work as long as the first port using protocol 5 is connected to one of the GPS. The GPS receivers were from two different manufacturers, the first being the Ublox 3DR receiver and the second a RTK receiver running as a normal GPS receiver. A UBlox GPS + Compass module is the most commonly used GPS for ArduPilot compatible autopilots. The kit includes GPS with a compass. User must assure that the GPS is Hello I’m using 2 CUAV C-RTK 9P as a DUAL GPS. The two GPS modules are configured as “moving baseline” (GPS_TYPE1 = 17 , GPS_TYPE2 = 18) and I am using GPS for Yaw / heading thanks to the RTK. The Holybro Unicore UM982 Dual Antenna RTK GPS provides high-precision positioning information and is capable of generating non-magnetometer moving baseline yaw determinations for autopilots. I am curious if there is any significant advantage over another setup in GPS blending. General. Most civil GPS receivers are using pseudorange data (C/A code) available on GPS L1 channel (1575. GPS_RATE_MS 200 GPS_RATE_MS2 200 SR3_EXTRA3 5 SR3_PARAMS 5 SR3_POSITION 5 For DroneCAN GNSS/compass modules:. For for example 1 the setup would be 2 GPS by the same vendor like a Here + and a Here 2 so one RTK and one not, a base would be used. 5 GHz) mounted also on the frame seems to interfere with Hello friends, today I made a flight with my quad 450 and dual GPS. I am using arducopter firmware 3. Huge difference in time to lock, HDOP. Also for Copter users we recommended against using two GPS Holybro RTK Unicore UM982 GPS (Dual Antenna Heading) Holybro RTK mosaic-H GPS (Dual Antenna Heading) LOCOSYS HAWK R1 RTK GNSS / R2 RTK GNSS + Compass; Note: Baud rate is auto-negotiated by the ArduPilot firmware, and Hello All, I am having bad problems with my 2 CUAV F9P GPS modules attached to my Cube Orange autopilot with ArduPlane v. I know it’s supported in Arduplane. copilot (JaSw) July 4, 2016, 2:16pm 1. 2014, 7:55am 1. GPS works fine. Receiving Format : GPS,GLONASS,Galileo,BeiDou,QZSS and SBAS. Only GPSs that report position and speed accuracy can be used Setting up dual GPSs is fairly easy. Momentary loss of GPS RTK and "PreArm: GPS 1: not health" Copter 4. i was trying to make dual gps work but only one gps leds are blinking and second gps is idle. I think ArduPilot with Dual GPS (blended) Blog. Did you ever find the answer to this question? amilcarlucas (Amilcar Lucas) January 10, 2021, 6:55pm 65. Telemetry is the really tricky part. rmackay9 (rmackay9) January 11, 2021, 1 IMO using dual GPS receivers introduces some inherent problems. Ground Control Software. gps, rtkgps, blended-gps. I am in search of advice on usage of GPS Yaw for a non drone application I am contemplating the usage of CUAV RTK 2HP heading module for an application other than drones. I save at the time the RAW signal of GPS2 ( ublox M8N) on a Sdcard in in datalogger and as GPs2 in the log files. Dual unit Serial GPS modules must be connected to ArduPilot via their (not the autopilots’s) UART1 connectors, DroneCAN modules via GPS data in those logs is very consistent with no drops in moving baseline yaw or significant changes in satellite reception. The Here+ GPS kit comes with a larger round GPS (also knows as the “Rover”) that should be mounted on the vehicle so that the round button is on the top and the faint arrow is pointing forwards. . Having multiple units, operating on the same band, in the same vehicle, can cause reduction of range in both units, even if using ArduPilot allows multiple compasses to be connected, but only three are used at one time. Both GPS’s work, pre-arm much easier. GPS 2 uses the same bus as the I2C 2 port. Gromitvt10 (Kyle) January 10, 2021, 1:53pm 64. ArduPilot Discourse Very strange dual GPS behavior. Initially flew with the default params using the disktheory and diskloading. Price is far better than dual F9P’s. 05 deg Hexsoon Dual RTK. 4. I’m planning to running dual gps as blend mode in AC 4. ; Other Flight Controllers/GNSS Modules . This setup is essential for determining orientation [image] ArduPilot has supported Dual GPS for quite some time but it has always only been using one or the other GPS (whichever had higher number of satellites). 13 and the issues still happens any solution please? My ‘rover’ GPS is connected to the GPS module port in the Pixhawk. instance1 and EKF2. Rotating the FC separately from the GPS module also affects the orientation display. And usually, only the primary compass is used, unless there are consistency problems with its readings versus other compasses and/or other The following parameter instructions assume Serial3 and Serial4 are used for serial connecting GPSes but any serial port(s) should work as long as the first port using protocol 5 is connected to one of the GPS. I followed the instructions in the The following parameter instructions assume Serial3 and Serial4 are used for serial connecting GPSes but any serial port(s) should work as long as the first port using protocol 5 is connected to one of the GPS. 5), and found that the GPS time is not output. I’m using two Here2 GPS modules, at first, I wanted to connect one of them to GPS1 port serie and the other to CAN1 in an Orange Cube . Both work fine when connected individually to the CAN port. It adopts built-in dual IMU redundancy and internal shock absorption structure design, which endows the Hi, I’m trying to get the best positioning accuracy without using RTK GPS. Note: Current firmware only support CAN 1 ,CAN 2 is not supported. Data Protocol : NMEA-0183 or UBX, Default NMEA HAWK R1 and R2 (with compass) is a L1+L5 dual-frequency RTK centimeter-level GNSS receiver designed for UAV applications. Still no indication on the HSI window of second GPS. I get the message “Err: EKF3 waiting for GPS config data” 95% of the time I try booting it up. Holybro RTK Unicore UM982 GPS (Dual Antenna Heading) Holybro RTK mosaic-H GPS (Dual Antenna Heading) Qiotek DroneCAN RTK-F9P GPS; Synerx MDU-2000 RTK + LTE GPS; GPS Driver Options; GPS Auto Switch; GPS Jamming Mediation; Advanced Uses. I will have a look into that and would be happy to implement it if it works. I am working with a CUAV Nora+ flight controller with ArduPilot Plane 4. Some of the source code is written broadly enough to be able to use more than 2, but I don’t think it’s a good idea to connect 3 or As far as I know ardupilot doesn’t support dual CAN GPS yet, so you need 1 GPS in CAN mode and another in I2C mode. 5 to 0. DroneCan GPS modules are connected to CAN-bus ports, which are 4-pin ports labeled CAN1 or CAN2. This system provides multi-band RTK with fast convergence times and reliable performance, concurrent reception of GPS, GLONASS, Galileo and BeiDou, and fast update rate for highly dynamic and high volume applications with centimeter-accuracy. Stephane_B (Stéphane) I also run dual airspeed sensors, but they’re different types (UAVCAN + 4525DSO, or 4525DSO + SDP33) so it may be more odd than I think. Hi, I have been using dual Here3 GPS on CAN for quite a while now. Google Drive file. set 3 baselines for comparison CA, carrier phase & RTK GPS receivers. GPS,Compass, Barometer, ADSB Receiver, LED, Buzzer, Safety Switch/LED, and Airspeed devices are automatically identified in the DroneCAN protocol - which is the node ID of the autopilot sending the commands to the ESCs so that there can be differentiation between multiple sources on the CAN bus. param (18. 1. 3 Here+ Rover module connected to the GPS port 3DR module connected to Serial 4/5 port and I2C port With the following params: SERIAL3_PROTOCOL = 5 SERIAL4_PROTOCOL = -1 GPS_TYPE = 1 GPS_TYPE2 = 0 I guaranted that I am having a single GPS reading (from the Here +) and a GPS - How it Works¶ GPS system is a Global Navigation Satellite System (GNSS). This is only evident by the constant beeping tones while flying, and looking at the log; the copter seems to fly fine. When I set the mode to UseBest (GPS_AUTO_SWITCH = 1), the GPS time is shown well under mission planner. Vibration Hello, I need help with configuring my flight controller Matek H743 Slim V3 and the H-RTK Mosaic-H (Dual Antenna Heading) system from Holybro. I do not have the aircraft parameters entered yet into the controller, really because I do not have the aircraft yet. I agree that running dual GPS receivers has its problem. Just connect the second GPS to Serial 4/5 and set the parameters as for your current GPS. I have used the The MP has a hidden feature to allow connecting to multiple vehicles by right-mouse-button clicking around the Connect button. Okay, thanks for the information. org) Ayush_Khare (Ayush Khare) April 29, 2024, 6:55am 7. I have put the Here 3+ on the CAN port, and the Here 3 on the I2C port. 8 on a Pixracer. if anyone can help.
