Achieving 30 cm Autonomous Positioning Accuracy with Nexteq Single-Frequency GPS Receivers

Y. Zhang, S. Lee, C. Chen

Abstract:	This paper will introduce Nexteq Navigation’s recently released Precise Autonomous Single-frequency (PAS) GPS receiver products. Nexteq’s PAS product development is focused on providing new products able to provide precise positioning solutions using only a typical GPS engine. Nexteq’s technology innovations (collectively known as Freedom technology) have resulted in unprecedented performance for its PAS products; 30cm autonomous GPS positioning accuracy. Nexteq’s PAS products also do not need base stations or depend on precise orbit and clock correction data from subscription service, making them outstanding candidates for all kinds of applications requiring precise position solutions and at unprecedented system simplicity and cost-effectiveness. Nexteq PAS products currently include the PAS110 and PAS120 series of receivers and are available for order. Testing results show that Nexteq’s PAS receivers powered by Nexteq’s Freedom technology can readily achieve 30 cm positioning accuracy. Nexteq’s PAS receivers also have outstanding repeatability in harsh environments, including under dense canopy or near buildings. This exceptional performance is appealing to applications conducted in challenging environments.
