Launched in 2003, Canada’s Precise Point Positioning (PPP) service, CSRS-PPP, continues to solidify its place as a world-class GNSS post-processing platform.
High-precision GNSS applications, such as real-time displacement monitoring and vehicle navigation, rely heavily on resolving carrier-phase ambiguities.
Some communities may consider old performance specifications of conventional/classical PPP, a rather niche technology, for static use with post-processing of measurements, resulting in tens of minutes for solution convergence to the decimeter level. However, there have been many performance advances, with more coming, affecting who uses the technology and how.
Tallysman Wireless and u-blox have partnered to develop PointPerfect precise point positioning real-time kinematic augmented smart antennas.
An all-of-the-above approach lead to the novel design of a GNSS rover systemthat can serve a wide variety of field surveying and mapping applications.
Precision agriculture — which uses data on field conditions to reduce inputs and increase yields and profits — is more than 30 years old. Today, all tractors from major manufacturers come equipped with a GNSS-based guidance system. In this month’s cover story, three industry managers give their perspective on precision agriculture.
Growing among the many options for GNSS corrections open to precision agriculture operators are tiered precise point positioning (PPP) services.
