SMALL LIGHTWEIGHT GPS RECEIVER
SLGRs were procured during the early 1990s to satisfy
immediate and urgent demands for a miniaturized version
of the Manpack. The sets procured using NDI procedures
were commercially available 1-, 2-, 3-, and 5-channel
receivers which operated using only the Standard
Positioning Service (SPS) signal (they cannot decode the
Precise Positioning Service (PPS) signal which provides
enhanced protection and accuracy for authorized users).
Their small size, limited battery drain, and low cost (at
the expense of PPS-accuracy) were highly desirable to
satisfy the urgent needs of mobile military units.
Selective Availability was turned off for this operation.
Their availability for use in Desert Storm made a major
contribution to US/UN Forces operations and proved
the value of GPS in supporting modern warfare. The SLGR
was manufactured by Trimble Navigation, Sunnyvale, CA.
