ZABALA, Mónica; LOPEZ, Franklin y ORTEGA, Ángel. Analysis and implementation of differential GPS in single and double configuration. Maskay [online]. 2017, vol.7, n.1, pp.41-48. ISSN 1390-6712. https://doi.org/10.24133/maskay.v7i1.343.
The standard positioning service (SPS), or undifferentiated measurements contains errors in its measurements affecting the final positioning solution of the receiver. The application of GPS differentiation techniques in simple (SD) and double (DD) configuration allow to eliminate errors that affect the GPS signal during to propagation path, among the most critical, are errors produced by the atmosphere and troposphere. Between the reference receiver and the mobile GPS receiver (rover) exist errors correlated in time and space according to the distance between them, the elimination of common errors increases the accuracy of the final solution. The application called DGPS-Lab is designed to execute the process of differentiation in both configurations and verify the results by minimizing the errors in the positioning through the implemented DGPS algorithm.
