Latest Satellite Tracking Priorities

SLR satellites are listed in order of highest priority to enable best coverage by the ILRS network.


The table below shows the number of normal points submitted to the EDC data centre by the ILRS network over the last 10 days. A priority is assigned to each satellite depending on its requirements for tracking. A priority setting of 1 is twice the priority of a setting of 2 which is twice as high in priority as a setting of 3.

A weighting is applied according to the number of Normal Points collected in the previous 10 days with the most recent data having a higher weighting, reducing its priority. This weighting is scaled by the satellite normal point bin length.

The satellites are tabled in decreasing order of their immediate priority for tracking. This table is updated every hour.
