Technical De!;ails:
A different type of differential GPS (DGPS) configuration is described and
compared to the standard DGPS configuration.
Implementation options for either configuration for space and return are
discussed.
Historical Background:
DGPS has been studied by numerous organizations as a highly sought after
accuracy improvement to standard GPS, particularly with selective availabilitv
applied. Flight tests of DGPS have been conducted by NASA LaRC and NAS,_, JSC.
Technology Maturity:
This is a first look at a different type of DGPS configuration.
results should be followed up with experimental field testing.
options will address use of current and near term technology.
Promising anaivsis
Implementation
Sponsorship and Funding:
Currently, the development of the DGPS For Space And Return is being pursued
on IR&D funding.
Biography: -
Stanley C. Maki, as Advanced Avionics senior engineering specialist, is
performing studies pertaining to low-cost application of the Global Positioning
System (GPS)/Inertial Navigation System to space boosters. He was responsible for
the Orbital Transfer V_hicle (OTV) avionics predesign with GPS application; more
recently, he has been involved in Centaur GPS experiments and system analysis for
the Multi-Path Redundant Avionics Suite (MPRAS) study, including a GPS
element. Mr. Maki has been continuously engaged in space vehicle guidance and
control since 1956, starting with design of the first space-flown solid-state digital
flight sequencer for the Atlas intercontinental ballistic missile. He has a BSEE from
the University of Minnesota and an MS in Engineering from the University of
California at Los Angeles.
