MSS 5000 Description 



The Maritime Surveillance System was developed by SSC for the Swedish Coast 

 Guard's ocean pollution surveillance and has been in operation in Sweden for over 20 

 years. The U.S. Coast Guard integrated the current version of the system, MSS 5000, 

 with its existing Motorola AN/APS-135 SLAR to modernize and extend the life of the 

 radar. MSS 5000 hardware includes the sensor data processor (SDP) for acquiring and 

 processing raw data, a data server that manages the local area network (LAN) onboard 

 the airplane and has redundant hard drives for recording data, a mission management 

 unit for displaying data, and a display station. There are also several ground-based 

 display stations for analyzing data and conducting operator training. 



MSS 5000 digitizes data from SLAR at a rate that corresponds to 30 meters of flight 

 tract<, with a resulting pixel size of 30 meters by 30 meters. MSS 5000 also acquires , 

 navigational data from the aircraft's global positioning system (GPS) to determine target 

 position. The geometric correction of slant range to ground range is calculated in the 

 SDP before the image is released to the LAN for display and recording. For purposes of 

 database management, MSS 5000 records the full SLAR range all of the time, 

 regardless of the range scale being used by the operator.
