Abstract
There is provided n interface apparatus for retrofitting a GNSS apparatus. The interface apparatus includes an antenna configured to receive a first GPS transmission, and an amplifier coupled to the antenna to receive and amplify a first GPS signal.
Claims20
A Global Positioning System (GPS) simulator coupled to a GPS receiver and an oscillator, the GPS simulator configured to:
- when a first timing signal and a position signal are received from the GPS receiver:
- generate a first simulated GPS signal based on the first timing signal and the position signal received from the GPS receiver;
- and
- when the first timing signal and the position signal are not received from the GPS receiver:
- receive a second timing signal from the oscillator;
- and
- generate a second simulated GPS signal based on the second timing signal received from the oscillator.
