Introduce
The TM7 is a small OEM surface mount GPS/GLONASS module that has been specifically designed for use in synchronization and timing applications. advanced timing features such as sawtooth error elimination,
programmable PPS output coupled with superior weak sinnal performance provides the TM7 with a significant edge over its competitors. The TM7 is an exceptionally small surface mount package with a highly integrated architecture that requires the minimum of external components allowing easy integration into host systems.
