GARCIA, J. G.; MERCADER, P. I.  e  MURAVCHIK, C. H.. Use of GPS carrier phase double differences. Lat. Am. appl. res. [online]. 2005, vol.35, n.2, pp.115-120. ISSN 0327-0793.

GPS carrier phase single and double difference characteristics are studied. Residual errors obtained from experimental results using independent commercial receivers for two antennas are analyzed. The potential of double differences for vehicle attitude estimation using a multiple antenna configuration with independent receivers is demonstrated. Receiver data synchronization is also given special attention.
