Abstract:	The US Global Positioning System (GPS) and other existing and emerging Global Navigation Satellite Systems (GNSS) enable more and more civil and military applications as the accuracy and coverage of the receivers steadily improve. While GNSS systems perform very well in strong signal conditions, their operation in many urban and indoor applications is not robust or even impossible due to strong distortions. The research community continuously explores new ideas and methods in an effort to design less costly, faster and more sensitive receivers. State-of-the-art receivers should be flexible to perform multimode tasks tailored to various conditions. The developers need reference receivers, associated Software Development Kits (SDKs), development platforms, simulators and testbeds to accelerate and facilitate their research. This paper presents such an integrated environment to reduce the development cycle and conveniently simulate and test receivers. The proposed testbed includes GPS signal simulator (transmitter) from National Instruments (NI) and several modules developed by authors for Labview, a development environment from NI. These are channel simulation module, a GPS software defined receiver, and Assisted GPS (A-GPS) support. The paper also describes the integration of hardware accelerators such as Field Programmable Gate Arrays (FPGAs) and Digital Signal Processors (DSPs). Receiver modules can be implemented in C/C++ or using Labview library components.
