NTRIP - achieve 1 cm Positioning using RTCM Correction Data
Solution #1: xpro NTRIP plus a Mobile Phone as Web-Interface
In order to make full use of the RTK capabilities of xpro GPS receivers, so called
RTCM information must be available.
There are basically 2 different ways to achieve this - either via a local base
station or alternatively via an Internet connection.
The important thing about base stations is that they have to be precisely
calibrated and reference data must be transmitted wirelessly to the so called
rovers.
The usable distance between the base station and the rover is limited by the
Rf-Power of the transmitter. This is ok for a closed proving ground, but for
cross-country rides on public grounds it is practically not a feasible solution.
xpro NTRIP avoids these pitfalls by accessing correction data via Internet.
A standard mobile phone can be used as interface between the remote
Homebase and the NTRIP-2-RTCM converter module of xpro NTRIP. This
dramatically reduces the need for a complex Rf-infrastructure.
Solution #2: Web-Interface based on the 4G/5G-Modem of xpro NTRIP
This special version of xpro NTRIP contains an internal 4G/5G modem thus
eliminating the need for a mobile phone.
The firmware of this modem acts as Web-Interface and converts the incoming
NTRIP data into the standard RTCM format required by xpro GPS receivers to
calculate accurate position data.
All you have to do is to purchase a standard SIM card for the xpro NTRIP
modem and enter the necessary settings about the next Homebase as well as
some Web Server data.
Power Consumption of xpro NTRIP is extremely low and all you need to do is to
connect a single cable to your xpro GPS receiver. Within a few seconds precise
position data will start streaming to your GPS device.
