5 Raw Measurement Recording and Post Processing
Raw measurement data logged on S100 RTK receiver is used for PPK and PPP processing. Sections 5-1
and 5-2 relate to these two types of post processing. How to obtain raw measurement data from S100 is
described in section 5-3.
5-1 Preparing for PPK
For Post-Processed Kinematic (PPK) calculations, both base data and rover data need to be available.
The base data can be (1) stored RTCM data received from RTK correction service or (2) stored RTCM data
received from another S100 RTK base; the rover data is the stored RTCM data from S100 RTK rover.
Refer to section 5-3 on how to log and obtain RTCM data on S100 receiver.
To perform PPK, files in standard RINEX format are needed. The logged RTCM data can be converted to
RINEX formats (2.01 – 3.03) using RTKLIB’s RTKCONV program. See Figure 5-1 a, b.
For reference Options window of RTKCONV is shown in Figure 5-1 c.
