Experiments with the Ublox F9P RTK GPS

This is a rather long video which presents some experiments with Ublox F9P GPSes as I get familiar with the Moving Base configuration. A Flight Controller is not involved in this video. The following configurations are demonstrated: • 1. 2 GPSes operating independently but using a common RTCM3 correction stream from a Fixed Base GPS (remote over the internet). • 2. One GPS is set up as a Fixed Base and the other is a Rover receiving RTCM3 corrections from it. • 3. Same as #2 except that the base GPS is configured as a Moving Base rather than a Fixed Base, giving precise heading, but not precise location. • 4. The Moving Base in #3 now is receiving RTCM3 corrections from a Fixed Base, giving us precise location and heading. • I am using UART2 on the F9Ps for the correction streams in all scenarios above. • Video Time Index: • 00:00 Intro • 03:02 The Setup • 04:28 Configuration 1 (and a lot of background info) • 24:00 Configuration 2 • 37:27 Configuration 3 • 45:58 Configuration 4 • 52:02 Closing Remarks • Note that I made a mistake in the baud rate statements shown at 48:28. I only changed the comment in the file to 115200. I did not change what really mattered, the hexadecimal value! Duh!! The last 2 lines of the file should read: • Flash CFG-UART2-BAUDRATE 0x1c200 # write value 115200 0x1c200 • RAM CFG-UART2-BAUDRATE 0x1c200 # write value 115200 0x1c200 • The file out on my Github site have this correction. • Links: • Ublox Moving Base Application Note: https://www.u-blox.com/sites/default/... • F9P Configuration Files on the Ublox Github Repository: https://github.com/u-blox/ublox-C099_... • My F9P Configuration File for Moving Base: https://github.com/ktrussell/Ublox-F9...
