Hi guys.
I have been using the Reach a lot recently. I have just got back from a very big survey job, measuring ground water monitoring well elevations with the Reach. The spread of well locations was fairly large with many obstructions about. NTRIP was not an option as the closest CORS was 150km away. So I post processed all 90 odd observations, each observation lasting 30seconds. Each point was cheacked by a third Reach device. The results were as always excellet with a maximum difference of 15mm between solutions.
But this mission of post processing 180 individual files lit a fire under me to get testing with the bluetooth ouput solution. I found really good results with the following combination:
- Setup a base Reach and issue RTCM data via RFD900 radios
- Setup second Reach in single mode to act as a backup base to use for post processing data if the communication in the field goes down.
- Setup a third Reach in rover mode on a plumbing pole with attached RFD900 radio to recieve corrections. Th solution should be outputted to Bluetooth NMEA.
Then on your Android phone: - Use Lefebure NTRIP Client (https://play.google.com/store/apps/details?id=com.lefebure.ntripclient) to connect to the bluetooth stream and send a mock GPS location to your phone
- Use Mobile Topographer Pro (https://play.google.com/store/apps/details?id=gr.stgrdev.mobiletopographerpro) to store, import, and stake out points as well as moving data. The app is pretty great with on the fly CRS translations, the abliltiy to apply offests, name points, and export to a variety of formats.
I think using this combination, we have a fully functioning Land Surveying tool.
