POINTSTAR

Global positioning system (GPS) antenna systems comprised principally of GPS radio frequency (RF) receiver modules, digital central processing units (CPU) and memory modules; terrestrial RF triangulation systems comprised principally of RF transmitter and receiver modules; digital CPU's and memory modules; inertial Navigation Systems (INS) comprised principally of accelerometer and gyroscope arrays; digital CPU's and memory modules; electronic compass modules (ECM's) comprised principally of multi-axis magnetic sensor and accelerometer arrays; digital CPU's and memory modules; and automatic vehicle location and tracking systems (AVLTS) integrating combinations of such GPS, terrestrial RF triangulation, INS and ECM with wireless communications equipment, namely, RF transmitter and receiver modules; each of the foregoing systems also provided with software for its operation and control
