Recently I was working on a project in a suburban area, using Reach RS2 GPS.
The mode of cmmunication I used between base station and Rover was LoRa.
Based on where i set up my base station (in close proximity (<15m) to single storey homes and about 800m away from cellphone towers), I experienced difficulty with the rover in receiving a steady rate of corrections, with favourable signal to noise ratio, from the base station.
I tried changing:
Frequency of communication in LoRa mode
Frequency of receiving RTCM3 corrections for GPS, GLONASS AND GALILEO
And also lowering Air Data rate.
All changes were made simultaneously on both Rover and Base.
Within a 1km radius of the base I experienced these difficulties with attempting to achieve a fix and as stated above…steady rate of corrections, with favourable signal to noise ratio.
If anyone has any suggestions they can give I would greatly appreciate it.
@wizprod I have experience with my RS +, the settings are correct. Less than 100 meters all clear, PDOP 1.3, age 0.4, there are no medium voltage lines and not fixed. I kept thinking if the frequency had changed, it also happened to me with ntrip
I have been able to play around with the settings (frequency, air data rate, RTCM3 messages) and get steady communication between base and rover in more urban and semi-urban environments that I have been working in, with several kilometers baseline.
I am assuming that my previous issue is based on a bad placement area for the base and based on interference from other communications as well as line of sight.
I was working on another project where there was moderately dense vegetation between the base and rover over a baseline less than 500 m. There was immediately some difficulty in getting good communication between the units. However, I was able to get a fix status for some points by lowering the air data rate, changing communication frequency and the update rate of the RTCM3 messages.
What is apparent is, working in such environments requires some trial and error in tuning the radio communications.
