We have One Reach RS2. Have updated firmware.
Set up to get data corrections from Android phone hotspot, tested at office with two devices.
Using Ntrip nearest LINZ/Geonet cors Wairau, 32km baseline to our office. Project is set to NZGD2000 Marlborough and NZVD
Issue 1, connection to receiver lost could not reconnect
First field test yesterday appeared to work ok. Let it sit in car for 20mins and went to use it again. Connection dropped because phone was out of range, could not re connect to hotspot.
Tried reboot phone and receiver, just would not work.
Tried receiver reset this morning, and eventually connected. But having trouble connecting a second time to hotspot. We are considering using a sim card in the receiver as a work around as connection to receiver via wifi seems ok.
Issue 2, Data does not fit control points
Data collected did not fit Linz control points, or fit relative positions. Ie control point 1 is 1.7m off, control point 2 is 800mm off. Repeated measure of previous topo points similar errors.
Could not test further due to connection issues. Site had 22km baselines.
Do we need to use a different NZGD projection option? Is there another issue?
Issue 3, Connection to other apps
Connected Bluetooth, paired. When establishing connection to reach in Field Genus Android (trial License) I get error “Unable to connect to Instrument.”
Connects with South Surv x and RTK (NMEA[0183) Bluetooth device. I don’t have a license so can’t test further. Also connected to survce win mobile south x11
- Using reach view 3 app. Had fixed positions 0.015m h and 0.015-0.020 v, low pdop, using around 15 satellites, Linz positionz real time service does not yet provide full satellite constellation corrections.
