2 Preparing for PPP

For some online Precise Point Positioning (PPP) service, older RINEX 2.11 format data is required; a minor

modification on converted RINEX file may be needed. Follow below steps to prepare RINEX file for

sending to online PPP service.

1.

Log and obtain RTCM data (see section 5-3)

2.

Use v.2.4.3 RTKLib’s RTKCONV program to convert the logged RTCM data to RINEX 2.11. Select

proper constellations and frequency bands the online PPP service uses; will then get a RINEX format

file *.obs. See Figure 5-3 a.

3.

Edit the output *.obs file, and modify the string “C2” to “P2” on about 13

th

line. See Figure 5-3 b.
