LISSA FM GNSS Test

Introduction

Test Description: Test the function of the GNSS through CDH, and the interface with CDH and payload for LISSA.

*NOTE* The FM GNSS receiver & LISSA payload are considered Controlled Goods and can only be handled by those with clearance under CGP. If you lack security clearance, the EM GNSS (UMS-0631) receiver is CoCom enabled and available to use (without the payload).

Completed: 

Documented by: Riley Sweeney

Resources Required:

• Tools: Required tools such as cleaning equipment, chemicals, jigs, hand tools, etc.

• Hardware and Equipment: UMS-0632 FM GNSS receiver, UMS-0651 FM GNSS antenna, FM FlatSat, LISSA Payload

• PPE: FM testing will likely occur in the clean room. Please follow all clean room safety guidelines. Please wear an ESD bracelet and use ESD mat when working with electronics.

Verification Activities: R-LIB-ADC-006-6968. R-LIB-ADC-100-6980, 6982. R-LIB-ADC-101-6984, 6981. R-LIB-ADC-110-6986, 6985. R-LIB-ADC-120-6987, 6989. R-LIB-ADC-130-6990, 6991. R-LIB-ADC-140-6992, 6993. R-LIB-ADC-141-6994, 6995. R-LIB-ADC-142-6996, 6997.

Pass Criteria: 

• The GNSS shall limit its current draw (R-LIB-ADC-006-6968). 

• The GNSS shall interface with the LISSA payload (R-LIB-ADC-100-6980, 6982). 

• The GNSS shall output PVT data at a minimum rate of 1 Hz (R-LIB-ADC-101-6984, 6981. R-LIB-ADC-110-6986, 6985. R-LIB-ADC-120-6987. R-LIB-ADC-142-6996, 6997). 

• The GNSS shall determine position within 25 meters (R-LIB-ADC-130-6990, 6991). 

• The GNSS shall provide position data in Earth-fixed coordinates (R-LIB-ADC-140-6992, 6993). 

• The GNSS shall provide a PPS signal to the payload (R-LIB-ADC-141-6994, 6995).
