简 介
The TM5 GPS receiver module is an integrated timing module powered by TM4 GPS receiver. It has been specifically designed for use in synchronization and timing applications, The TM5 has an on-board programmable NCO oscillator that outputs a synthesized frequency up to10 MHz that is steered by the GPS receiver. The TM5 has a self survey mode of operation that allows the receiver to enter a position hold mode to allow accurate timing to be continue with only one satellite being tracked. The output frequency is highly accurate and can achieve full PRC MTIE performance. It can also track satellites and provide GPS synchronization in weak signal areas such as indoor applications. This reduces the need for high antenna placement in many environments.
