PC=win10, lots of 64bit power, 16 GB ram , 8 T HD, 4k display…
with Norton security.
I just received 2 alphas for evaluation and use; Std and lite set.
- rtviewer craches in win 10 after connecting. I tested full screen->crash.
I can not get or buy the license. I enabled rtviewer in Norton and run it as Admin.
(Also I tested with old win7 having some problems with windows updates and NET.
it gave notice of missing net framework involving internet features.)
- I tested standard and lite kit antenna. Both had low accuracy 15-3,5m max 8 satellites. I tested $100 Garmin Glo at the same spot and it gave 1,5m + more satellites, like 11. Glonass is here better than GPS. I do not know if Glonas is used by Alpha now. Garmin uses more satellites even with less signal and Alpha drops level under 30 satellites away. Is there a limitations without license for accuracy and satellites? Or is the receiver just bad?
- If I buy the licence , do I get this to work? If the software worked?
I noticed that when antenna was close the Alpha and USB power pack, the accuracy was bad. I thought it could be EMI on GPS frequency. Alpha+powerpack is in plastic box and my intention was to fix the antenna to this box too.
- I tested the Android Lefebure NTRIP client also. I could not configure and test yet the local NTRIP correction server fully. Because the Gps position is not accurate. Also the program did not save the setups like NTRIP ‘stream’ and I have to enter setups every time I enter the program. With Huawei M2-801L 8" notepad. I understand it is not your program, but I have no another somehow operational client.
I tested another Android client, RTKGPS+, too, but I could not use it because it could not read/input Alpha data stream as a Rover, propably because NMEA protocol could not be selected amount the selection. After 8 h I gave up this complicated software with limited information.
For now I can use this Garmin Glo and it is smaller and more accurate.
Is there any way to get even 25 cm accuracy with one Alpha + Lefebure NTRIP client and use local NTRIP server, which is very accurate, it is close, gives corrections and base location and is maintained by goverment here.
If this works someday I think I could use 2 Alphas: base + rover with 4G connection on the site and use reference point with base station. But better would be use local public NTRIP with fixed IP server and professional equipment. Now it seems that next week I have to call and order a man with a Trimble to locate the gps coordinates.
