Success Stories: GPS Timing Integration for Small Form Factor PDRS

Spectracom’s TSync bus-level timing platform was integrated into a new small, rugged, Passive Detection and Reporting System (PDRS) to receive GPS, discipline an onboard rugged ovenized crystal oscillator and generate high precision time and frequency signals for system synchronization. It also delivers GPS coordinates for the system.

The development of the system greatly benefited from Spectracom's customization-to-COTS approach by adapting the platform into a standard VPX-based card without the need for non-recurring engineering charges. It offered the necessary ruggedization, small size, and low weight and power consumption to meet the goals of system portability, and is available with secure SAASM GPS.

Success Stories: Synchronizing Services With a Public Safety Answering Point Terrebonne Parish (Louisiana) relied on wall clocks to provide less-than accurate time. As a result, CAD reports were depicting fire apparatus arriving prior to the call being received. Police and deputies’ times were equally as skewed.  The Parish decided to purchase an Orolia NetClock solution.  Terrebonne Parish now has the ability for its agency and remote agencies to add numerous items and offices for synchronization, ensuring that all their reports are accurate. pdf - 126 KB

Success Stories: Dawson Creek Fire Department The Dawson Creek Fire Department had a problem. The clock on the wall showed a different time than the computer clock, which had a different time than devices recording the mergency calls routed through the department. Times noted on manual documentation did not always match times from the recording devices. DCFD was not using a true official time reference to maintain consistent records as is the best practice in public safety answering points. pdf - 147 KB

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
