PPP-BayesTree

This repository contains a modified version of GTSAM, which has been updated for GNSS data processing. To enable RINEX file reading and GNSS observation modeling, the GPSTk library is utilized. A detailed description of the modification made can be found in "Evaluation of Kinematic Precise Point Positioning Convergence with an Incremental Graph Optimizer". This software has been cleared for public release by the USAF Case # 88ABW-2018-0905

How to Install

1) Requirements/Recommendations

Required

  • Boost --> sudo apt-get install libboost-all-dev
  • CMake --> sudo apt-get install cmake

Recommended

  • Intel TBB --> sudo apt-get install libtbb-dev
  • Intel MKL

2) Clone repository to local machine

  • PPP-BayesTree --> git clone https://github.com/wvu-navLab/PPP-BayesTree.git

3) Build

cd PPP-BayesTree/truck/gtsam;
mkdir build && cd build;
cmake --CMAKE_BUILD_TYPE Release ..
make

4) Test

As an example, a sample data-set is provided. This data-set was collected at West Virginia University on-board a small, fixed-wing UAV --- this platform is known as the Phastball. The two images below, we provide an in-flight image from the Phastball, and the flight profile.

Using the provided data-set, the PPP Bayes tree example can be utilized as shown below.

cd ../data
./../build/examples/pppBayesTree -c phastball.conf
