Tightly Coupled Integration of Ionosphere-Constrained Precise Point Positioning and Inertial Navigation Systems
The continuity and reliability of precise GNSS positioning can be seriously limited by severe user observation environments. The Inertial Navigation System (INS) can overcome such drawbacks, but its performance is clearly restricted by INS sensor errors over time. Accordingly, the tightly coupled integration of GPS and INS can overcome the disadvantages of each individual system and together fo...
متن کاملTightly Coupled Integration of GPS Ambiguity Fixed Precise Point Positioning and MEMS-INS through a Troposphere-Constrained Adaptive Kalman Filter
Precise Point Positioning (PPP) makes use of the undifferenced pseudorange and carrier phase measurements with ionospheric-free (IF) combinations to achieve centimeter-level positioning accuracy. Conventionally, the IF ambiguities are estimated as float values. To improve the PPP positioning accuracy and shorten the convergence time, the integer phase clock model with between-satellites single-...
متن کاملPrecise Point Positioning for timing
In recent years, many national timing laboratories have installed geodetic Global Positioning System receivers together with their traditional GPS/GLONASS Common View receivers and Two Way Satellite Time and Frequency Transfer equipments. Many of these geodetic receivers operate continuously within the International GNSS Service (IGS), and their data are regularly processed by IGS Analysis Cent...
متن کاملPrecise Positioning and Attitude Determination of Microsatellites using a Software-Defined Radio
Current GPS technologies for satellite navigation are relatively costly, heavy, and utilize a high amount of power. This makes such systems difficult for small satellites to support. In this paper, we describe a lowcost, low-weight, low-power GPS navigation system to support smaller satellites. A key component of our solution involves our patented TIDGET-based receiver design, which takes a bri...
