Vallado and Carter showed that highly accurate orbit determination
is possible with dense observation data for 120 s (a few hundred observations per satellite pass) .
In the orbit determination
, especially with the kind and quantity of modern data, statistics play an important role nowadays .

Our interest is to understand how sensitive the orbit determination
is to the ocean tides and how precisely the ocean tides should be modeled.
Topocentric orbit determination
: algorithms for the next generation surveys.
Each least squares orbit determination
run was initialized using the JSpOC TLE, and each came to a convergence with close resemblance to the TLE.

TerraSAR-X precise orbit determination
with real-time GPS ephemerides.
A modellization piece that is often used in precise orbit determination
is given by the socalled empirical accelerations.
