Test Platform Handles Complete A-GPS Design Cycles

Supporting the entire development lifecycle of assisted global positioning system (A-GPS) devices from initial R&D through conformance testing, the 6103 AIME/CT test platform addresses the emerging development and conformance test requirements for A-GPS mobile handsets. Based on the 6103 AIME and AIME/CT test platforms, the test system relies on the 12-channel NLC–L1–AGPS Constellation Simulator from Navigation Laboratories to emulate the entire 24-satellite GPS constellation and perform modeling of all associated GPS satellite and vehicle effects. The system supports both MS-Based and MS-Assisted positioning methods, as well as conventional GPS, and provides analysis of the pseudo-range and latitude/longitude location response for the unit under test. Support for RRLP messaging allows simulation of standard A-GPS call flow location requests for the control plane. For the user plane, it provides the ability to support TCP/IP and the secure user plane. The system currently supports all 33 of the A-GPS test cases listed in TS51.010 at both GCF work item 16 and PTCRB RFT 34. For more details, call AEROFLEX INC., Plainview, NY. (800) 835-2352.
