polarity test
Definition
test to verify the correct polarity of the functional chains (mainly AOCS) or equipment of the space segment element from sensors to actuators, through a number of interfaces and processing.Notes
- NOTE 1 A polarity error can be generated throughout the development process: interface documentation, design, H/W manufacturing, S/W development, satellite AIT, satellite database.
- NOTE 2 A polarity error can be generated by any element of the functional chain: sensor or actuator design, sensor or actuator mounting, harness, interface units, software algorithms.
- NOTE 3 Polarity inversion on Safe Mode control loops can cause a satellite loss.
- NOTE 4 4 This term "sign test" is synonymous.
