The SATELLINE-M3TTL1 is a compact transceiver module housed in a stainless steel enclosure and designed with integration in mind particularly suited to RTK applications.

Fully compatible with the SATELLINE 3AS/EPIC and other M3 Units. It has an RS232 serial interface and the secondary low voltage TTL interface.  It has an MCX antenna connector and the antenna circuitry includes filtration of GSP frequencies, this is particularly useful in RTK applications

The SATELLINE-M3TTL2 is very similar except that it has an MMCX antenna connector and the D connector is in the same position as a standard 3AS radio modem, it is lighter and smaller and is in an aluminium enclosure rather than stainless steel.  It too is compatible with a SATELLINE 3AS

Complies with the following international standards

  • ENTS 300 113 and EN 200 220-1 (radio requirements)
  • EN 301 489 (EMC requirements)
  • FCC part 90
