Integer aperture ambiguity resolution based on difference test

Journal of Geodesy, 2015
Carrier-phase integer ambiguity resolution (IAR) is the key to highly precise, fast positioning and attitude determination with Global Navigation Satellite System (GNSS). It can be seen as the process of estimating the unknown cycle ambiguities of the carrier-phase observations as integers. Once the ambiguities are fixed, carrier phase data will act as

Integer-sided Triangles and the SSA Ambiguity

The Mathematics Teacher, 1987
The problem of determining integer-sided triangles that contain a 60-degree angle was mentioned by R. G. Dearborn (1985), In this article I shall derive some general formulas for resolving this problem; these include Dearborn's result as a special case and have several further ramifications, including a connection with the well-known “SSA ambiguity” in

Kinematic GPS: resolving integer ambiguities on the fly

IEEE Symposium on Position Location and Navigation. A Decade of Excellence in the Navigation Sciences, 2002
In the kinematics GPS (Global Positioning System), the initial integer ambiguity must be resolved either by a static survey over time or by instant calibration with a known baseline or an antenna exchange. It is pointed out that, while these standard methods require the maintenance of a baseline strategy to an Earth-fixed reference frame during the ...

Direct Ambiguity Resolution Using Integer Nonlinear Programming Methods

1996
This paper presents a new and efficient strategy for ambiguity resolution on the fly. The new approach is based on the method of Integer Nonlinear Programming (INLP). After discussing some typical methods for INLP, ambiguity resolution of GPS phase measurements based on the Integer Least-Squares Method (ILSM) is formulated as a problem of INLP.
