Techtotop/Taidou
SatPulse supports modules from Techtotop, known in Chinese as Taidou.
The vendor name used with the --vendor option and vendor key is techtotop or taidou.
These modules all use the binary SDBP protocol, which is similar in style to the UBX protocol and handles both periodic data and configuration.
For these modules, SatPulse supports:
- decoding of the SDBP packet format (packet format tag is
SDBP) - conversion of messages into the SatPulse device-independent data model
- low-level configuration
- message files for configuration
- a
sdbpmessage type in message files, with correlation of responses
SatPulse has been tested with the T303-5D, which is an L1/L5 timing module.
