2 years ago Hi,
Please correct me if I misunderstand what you want to do but you have satellite clocks, orbits, phase and code biases I presume and just want to compute the daily static position of a set of stations correct? This is basically just doing PPP within groops. The only thing you have to adapt is changing the parametrization from kinematicPositions to staticPositions and make it unconstrained within the no-net constraints (=0 value meaning it is unconstrained).
Regarding the no-net constraints and parametrization information can be found within Strasser 2022 especially chapter 6.9.1 regarding the no-net constraints.
Best regards, Patrick
Description
Hello developers, I'd like to process IGS stations with fixed satellite products, and get static positions. In this case, should I add no-net constrains to the normal equation? Since no-net constraints are required when estimating satellite orbit, I'm not sure whether no-net constraint would impact(improve) static position estimation when fix satellite products. By the way, station postion should be tightly constrained when estimating satellite products, I haven't found that constraint. Is that no-net constraints? Many thanks!
