Reach nmea rs232 output with rfd900+ ag GPS guidance

Reach Rover to Geophysical Instrument Integration

I’m trying to understand if this is possible and what configuration I need in terms of hardware and ReachView settings to make this happen? GPS Base - GPS Rover, RTK corrections via radio Rover NMEA out to geophysical instrument via RS232 serial (no other options exist here on geophysical instrument side) Rover NMEA out to Android Phone via Bluetooth Power to rover via USB Log rover and base too I’ve pointed out on my diagram the integration points where I’m unclear as to whether this is feas…

you can read here for using uart for rfd and output…

Rfd900 coverage/reach

Does somebody use rfd900? you you tell me something about coverage/reach in praktikal use with standart 3 dbi antennas? regards Andreas

if you can use higher duty cycle in your country (100 %) you can decrase airspeed look here:

RFD900+ theoretical Air Data Rate minimums for each ReachView u-blox configuration file:

GPS_1Hz, 1758b/s → ADR = 4
GPS_5Hz, 7899b/s → ADR = 8
GPS_10Hz, 14744b/2 → ADR = 16
GPS_14Hz, 20430b/s → ADR = 32
GPS_GLONASS_1Hz, 2458b/s → ADR = 4
GPS_GLONASS_5Hz 11584b/s → ADR = 16
GPS_BEIDOU_1Hz not tested
GPS_BEIDOU_5Hz not tested
reach_raw, 15270b/s → ADR = 16
