A positioning system incorporating a time offset into the pseudo random noise codes. Incorporating the time offset, a transmitter from a pseudo satellite sends pseudo random noise codes to a receiver which recognizes the pseudo random noise codes with the offset. The offset is typically done as one or more hours. Knowing the offset value, the receiver then acquires the signal, and uses it to determine position, distance, etc. The use of an offset allows conventional receivers to ignore the time offset signal by selecting a time offset value which is greater than the searching time allowed in the conventional receiver. Equipment capable of recognizing the time offset signal is capable of thereby ignoring and/or distinguishing incoming signals from other sources.

GPS augmentation using time offset code modulation

Wireless integrated miniature sensing stations which can be organized into a communicating network allow sensitive detection and analysis of vibration, infrared radiation, sound, or other physical signals indicative of an intruder or condition to be monitored over a wide area. The sensing stations operate on low power and include a sensor or sensors, a digital signal processor, a microprocessor, and a wireless transceiver for communication. Network communication is facilitated by multiple relayed transmissions from station to station.

Unexpected frequency shifts in GPS receivers are compensated by utilizing a shock detector or temperature transient detector. The detector can be utilized with a GPS receiver and provides a signal to adjust the signal-search algorithm. The signal-search algorithm is able to acquire or reacquire a satellite signal more quickly when adjusted by the shock detector. The receiver can be utilized in guided munitions and other vehicles which are susceptible to temperature transients and mechanical shocks.
