Practical testing various configurations of the new ARF GNSS System against one of our existing units

N. Tripcevich, Date: March 2020

New GNSS: EMLID Reach RS2 Survey Kit

Existing GNSS: Trimble Geo 6000

Testing various configurations including:

  1. WAAS SBAS correction only
  2. NTRIP Correction against California CRTN Network using the mountpoint in downtown Berkeley SRB1_RTCM3
  3. NTRIP Correction against CSDS CSVSN Network
  4. RTK Correction against nearby Base (EMLID Only).

Results

Configuration solution status lateral rms sample count distance to base Base Satellites
RS2 No WAAS Single 0.2869 431
RS2 CRTN FIX 0.0037 114 896 m
RS2 CSVSN test1 FIX 0.0067 375
RS2 CSVSN test2 FIX 0.0055 239

Thousands of GNSS Real-time Reference Base Stations are available publicly online that can be used with our GNSS units using NTRIP provided that the device is on the internet. You will need either cellular broadband (create a hotspot with your cell phone) or a satellite internet connection hotspot. A map showing the UNAVCO stations can be viewed online https://www.unavco.org/instrumentation/networks/status/all/realtime

For example the UNAVCO Realtime station in Berkeley is called P224 https://www.unavco.org/instrumentation/networks/status/nota/overview/P224

Instructions for configurations (request email for login/passwd, etc) are here https://www.unavco.org/data/gps-gnss/real-time/real-time-use-instructions.html
