System Diagrams: Indoor GPS Location These diagrams describe the issues relating to GPS for indoor positioning and navigation. 
  • Typically you'd consider a pseudo-satellite appriach but which require a specially designed receiver
  • A GPS RF simulator could generate signals that a GPS receiver would interpret as a single (pre-programmed) position (or trajectory) which could be useful for "zone positioning"
  • A GPS repeater would do something similar but the GPS receiver would always interpret at the position of the outdoors GPS antenna

Technical Notes and Briefs: Sensor Simulation with GPS Testing GPS simulators are able to test the integration of a GPS/GNSS receiver into a nav system by generating signals corresponding to virtually any condition including vehicle dynamics. They can also generate signals for other sensors for a comprehensive system test. As the simulator generates satellite data for a given trajectory, it simultaneously calculates position and attitude data in six degrees of freedom in real-time; forward/backward, left/right and up/down as well as the rotations about three perpendicular axes, pitch, yaw, and roll; which can be queried and used in integrated test systems. pdf - 181 KB

Technical Notes and Briefs: Vehicle Modeling with GPS Simulation Testing The typical application for a GPS simulator assumes an unobstructed view of the satellites. For advanced testing applications, it is possible to model the placement of the GPS antenna relative to the vehicle body. Starting in application software version 6.2 of the GSG series GPS simulators, vehicle modeling allows the simulated satellite signals to be blocked by the vehicle. Applications of this feature include aircraft maneuvers. pdf - 2 MB

Technical Notes and Briefs: EpsilTime™ Synchronization Algorithm Spectracom time and frequency synchronization management algorithms, like EpsilTime™ used in models EC20S and EC22S, uses smart predictive technology to mitigate the effects of inherent GPS and oscillator noise, improves accuracy if GPS is lost(holdover), and corrects drift in the 10 MHz and 1PPS outputs simultaneously. That means there are always 10 million frequency cycles between every one pulse-per-second. pdf - 122 KB

Technical Notes and Briefs: How to Restore Analog Radio Coverage Stolen by Narrowbanding Coverage problems were created when analog systems were narrow-banded. Mission critical communications demand the ability of officers in the field to communicate when necessary. Simulcast and receiver voting can improve talk-in with maximum return on your investment – which is far less expensive than a major infrastructure build-out to add channels or a forklift radio change to P25 or DMR. pdf - 523 KB

Technical Notes and Briefs: In-Field Coax Connector Test Using the Path Align-R A Path Align-R test set can be used in lieu of expensive cable sweeping equipment. Simply attach the Path Align-R to each end of the connectorized coax and measure the “Cable Loss” at the specific frequency the cable will see during operation. Also, if more than one coax is going to be attached to the tower, you can compare the “Cable Loss” of each coax before they are installed. pdf - 205 KB
