GPS+GLONASS Surveying

William Martin and Jonathan Ladd

Abstract:	There has been a considerable amount of discussion recently regarding the feasibility of combining GPS and the GLObal NAvigation Satellite System (GLONASS) to provide enhanced performance for surveying applications. This has been primarily due to the technical challenges of optimally combining data from the two dissimilar satellite systems. We will show that GPS+GLONASS technology can indeed deliver significant advantages for surveying. These advantages include dramatic improvements in satellite availability, solution integrity, and operational productivity without sacrificing the measurement accuracy currently achievable with precision GPS systems. We will present real-world field results based on data collected using commercially available equipment which will demonstrate that single-frequency GPStGLONASS surveying rivals the performance of more expensive dual-frequency GPS systems in many operational environments.
