Mission and Systems Level Requirements Impact Analysis

The ArcticSat project will use similar aspects to those of the Iris project.

A difference between the two projects is the transmission elevation angle. The Iris project had a minimum elevation angle of 10 degrees, whereas the ArcticSat project has a minimum elevation angle of 20 degrees.

This analysis is driven by the following mission and system-level requirements:

R-ARC-BUS-167: The bus shall transmit processed data to the ground station at every pass over the ground station with an elevation of over 20 degrees.

Additionally, as from Iris, R-COM-0140, the communications system acquisition of signals shall occur at a minimum elevation angle of 10 degrees.

For more information about these requirements, please refer to the registry in Valispace.
