TOP168 RTK GNSS receiver can reach up to 1.4cm positioning accuracy. It integrated a u-blox ZED-F9P RTK Module with a high-precision multiband “ufo” antenna. The 168mm antenna can effectively reduce the GNSS signal “phase delay” or “missing phase center” issues, which made TOP168 an excellent candidate to be set up as a RTK base station.

TOP168 has 184 channels, receiving data from 4 constellation satellite positioning systems including GPS, GLONASS, Galileo and Beidou. It outputs RTCM and NMEA0183 protocol via USB and Bluetooth.

Setup your own cost-effective NTRIP / CORS solution

Is your NTRIP service subscription plan too expensive to afford? Or if your most available NTRIP Caster mount point is too far away? If the answer is yes, you should set up your own NTRIP / CORS solution.

Below is the end to end RTK base station NTRIP solution. It consists of
1 x TOP168 RTK GNSS Receiver
1 x RTKLib's STRSVR Ntrip Server software (free)
1 x GeoAstra Internet NTRIP Caster Service (free) NTRIP / CROS System Diagram

Your cost of the solution is just a TOP168 RTK GNSS receiver ($699), a Windows computer and Internet access.

To set it up, please follow the below step by step instructions:

Build your very own NTRIP RTK Base with just an RTK GNSS Receiver and 5 minutes.

The solution is easy enough, more people could set it up in a few hours. After that, you will have a NTRIP caster mount point which could be closest to you. The RTCM correction data it provides could help your rovers nearby get very incomparably high accuracy.

We tested the above setup & got a pretty satisfaction result. we achieved 0.0141m horizontal accuracy in our RTK rovers. Please refer to the below screenshot.

RTK base station calibrating options

Option 1: Survey-in

If you deploy a TOP168 in a temporary location, you could use the “Survey-in” calibration option. TOP608 will acquire the position by itself and run as a RTK base station in a few minutes.

Option 2: Fixed Mode

If you deploy a TOP168 in a permanent location, you could use the “Fixed Mode” calibration option. You could use TOP168 to collect hours of RAW data and send it for the PPK process. (There are many free PPK services online these days. For example: CSRS-PPP ) After receiving the PPK process result, you could manually key in the location data into the TOP168. This option could need more time, but it is more accurate.

RTK reference station ARP(Antenna Reference Point) setup could never be so easy.
