5.7 Pacific Crest and TRIMTALK compatibility
5.7.1 General
SATELLINE-M3-TR1 radio modem module supports additional to the original SATEL 3AS data
transfer also:
o Pacific Crest compatible data transfer over the air, if the opponent Pacific Crest modems
operate in the transparent mode/FEC ON/Scrambling ON that is the most common setup
among RTK applications. The other modes are currently not supported.
o TRIMTALK
®
450s compatible data transfer over the air.
SATELLINE-M3-TR1 radio modem module provides the following radio compatibility settings:
o Option 1 for Pacific Crest 4-FSK modulation, Transparent mode/FEC ON/Scrambling ON.
o Option 2 for Pacific Crest GMSK modulation, Transparent mode/FEC ON/Scrambling ON.
o Option 3 for TRIMTALK GMSK modulation, Transparent mode
o TrimTalk450s(T) = TrimTalk450s GMSK (Rx fitted to Trimble transmitter)
o Pacific Crest-FST = Pacific Crest Transparent FST (4-FSK)
So far, only the transparent mode is implemented, since it is the most commonly used and
recommended by the user manuals. The ARQ based protocols with ACK/NACK schemes are not
preferred in RTK applications that apply one-way communication.
The implementation of Options 1, 2, 3 is based on the reference measurements and the
available public data of the following radio modems manufactured by Pacific Crest
Corporation: RFM96W, PDL HPB, PDL LPB. TRIMTALK is a trademark of Trimble Navigation Ltd.
