LabPro
This is out premium product. In the LabPro, our digital hardware and RF up-conversion is integrated with our full featured Tapestry software within a rugged and powerful Windows 2000 computer system.
The LabPro is designed to support hi fidelity analysis and simulation test functions. As a valuable support tool during the design phase of the project in addition to the implementation phase. The LabPro can test the following receiver and related navigation functions:
 |
Performance under dynamics, |
|
Acquisition and time to first fix, |
|
Navigation performance and fidelity, |
|
Basic functionality, BIT, operability, |
|
Basic receiver functions, data decoding, range and carrier processing, |
|
MOPS certification testing, |
|
Jamming sensitivity. |
To perform the functions, all LabPro systems include the following capabilities;
| A powerful six-degree-of-freedom vehicle motion generator. You may select maneuvers from a list, create with a mouse or joystick, or upload a formatted motion file from your own software. |
| Complete Navigation Data (NavData) message modeling. An imported Holloman Almanac initializes subframe 1-5 which then serves as a template for the Satellite Navigation Data Editor. With this editor, the contents of the Navigation Data is presented in engineering units accessible to the user. With the Navigation Data Bit Editor the user controls the raw binary data stream at the bit level. |
| Vehicle silhouette and antenna gain pattern modeling. |
| Atmospheric modeling. This includes the ICD-GPS-200 Klobuchar model and the RTCA-229C Waas algorithms. Exact model matches for most GPS receivers is provided. |
| Serial Outputs of Altitude, Ground Speed, heading, and other auxiliary dynamic parameters. |
| A powerful GPS constellation editor with flexible satellite specification algorithms and strategies. |
The LabPro contains an Ovenized Crystal Oscillator (OCX) with a phase stability of -160 dBm at 10 KHz, a programmable 1-PPS synchronized within nanoseconds to UTC rollovers, and optional, remote control, data interfaces implemented in GPIB, Ethernet, RS232, and ScramNet. The LabPro can be combined with or Multifunction Input/Output PCI expansion board (MFIO) to simulate scenario based hardware outputs of vehicle turn rate, acceleration, wheel speed pulse trains (four wheel), inertial reference unit
system housed in a ruggid rack mounted chassis with a state of the art integrated with the Rockwell Collings PCSG. The LabPro uses the Base System Configuration of our software integrated with a 10 channel Rockwell Collins PCSG. This system provides a full 6-DOF-motion capability to the simulated host vehicle. Base features include download and customization of the Holloma/Yuma almanacs, real-time antenna gain patterns, RAIM, constellation selection control, and closed loop receiver data feedback, serial data outputs such as RTCM 104 or SCAT-1 formatted differential GPS data, etc. Power adjustment is provided over a dynamic range of 50db in 0.3dB increments. The LabPro can prvide multiple vehicle capability, and has built in dynamic scenario generation for vehicles ranging from automobiles, ships, high dynamic aircraft and orbital space vehicles. The system can be operated either in a scenario based script mode or real-time via mouse or an optional joystick interface. The system can be upgraded to Y code with proper authorization via an expansion daughter card.
