An optical tracking network, the Optical Wide-field patroL Network (OWL-Net), has been developed to maintain the orbital ephemeris of 11 domestic low Earth orbit satellites.
The schedule overlapped events were occurred in the scheduling of the OWL-Net with reduction of the optical observation chances.
A short-arc observation strategy for the OWL-Net was tested to reduce schedule overlapped events with the optical observation simulation and the orbit determination.
In the full-scale optical observation simulation from January 2014 to December 2016, the most frequent overlapped events were occurred 127, 132, and 116 times in the 4th, 34th, and 18th weeks of 2014, 2015, and 2016, respectively.
The average number of overlapped event for three years was over 10% for the whole observation chances of five stations.
Consequently, the short-arc observation strategy reduced the schedule overlapped events for every observation target of the OWL-Net.
In case of the 5 s and 10 s cases, the most schedule overlapped events were removed.
The test results of the orbit determination results show that the most maximum orbit prediction errors after seven days are maintained at <10 km in the in-track direction for the short-arc observation simulations.
The results demonstrate that the short-arc optical observation strategy is more optimal to maintaining the accuracy of orbital ephemeris with more observation chances.
