Analysis of the SiRF Binary protocol

The article presents an analysis of decoded binary measurement data recorded by devices equipped with SiRFStarIII GNSS modules. The devices have the capability to operate using the advanced SiRF Binary protocol, which allows access to extensive format messages and parameters of the GNSS navigation receiver. To verify the potential for using measurement data obtained via the SiRF protocol, a simultaneous test measurement was conducted for the purpose of this article using three GNSS navigation receivers. The receivers simultaneously recorded measurement results at a reference geodetic control point with known coordinates.The proprietary SiRFLogger application was used to decode the recorded binary format messages. Decoding the SiRF binary protocol, compared to existing NMEA, RTCM, or RINEX standards, provides additional information regarding the operational correctness of the GNSS receiver, thereby enabling a broader assessment of navigation parameters than previously possible.
ANALYSIS OF SIRF BINARY PROTOCOL
In the article the analysis of decoded binary measurement data recorded by SiRFStarIII-equipped GNSS devices was performed. These devices have the ability to use advanced SiRF Binary protocol, therefore the access to the sophisticated messages of the format and the parameters of the GNSS navigation receiver is possible. In order to verify the usability of measurement data obtained using the SiRF protocol for the purpose of making the article the simultaneous test measurement with the use of three GNSS navigation receivers was carried out. The receivers were performing simultaneous measurement on the reference geodetic point, which coordinates were known.
For decoding of the recorded binary messages the authors’ SiRFLogger application was used. Decoding of SiRF binary protocol, in comparison with NMEA, RTCM or RINEX standards, gives additional information regarding the correctness of the GNSS’ receiver operation, and thanks to this the assessment of the navigation parameters in wider spectrum is possible.
