Project Title:

Assessing dual-frequency multi-constellation SBAS and SBAS-aided Precise Point Positioning (PPP) for surveying applications

Organisations Involved:

  • NSW Department of Finance, Services and Innovation (DFSI) (Spatial Services NSW)

This project aims to quantify the positioning quality achievable via SBAS and PPP in a practical scenario. It will evaluate the benefits for the surveying and spatial profession and other users of real-time positioning infrastructure, particularly in remote locations with intermittent or non-existent mobile telephone coverage.

Project Title:

Assessing dual-frequency multi-constellation SBAS and SBAS-aided Precise Point Positioning for survey and/or mapping applications in Victoria

Organisations Involved:

  • RMIT
  • DELWP (GPSnet)

SBAS technology can potentially be of benefit to surveying applications, particularly in remote locations where mobile phone coverage is patchy or non-existent. In a practical scenario, this project therefore aims to assess the positional accuracy, repeatability and reliability of dual-frequency multi-constellation SBAS and SBAS-aided Precise Point Positioning for survey and/or mapping applications in Victoria.

Project Title:

SBAS applications for low accuracy rural cadastral surveys

Organisations Involved:

  • University of Otago
  • Trimble New Zealand Solutions

Rural cadastral surveys have an important role in New Zealand’s economic development as they facilitate land transfers, the registration of Queen Elizabeth II National Trust (QEII) covenants and easements for walking tracks. Otago University will evaluate the effectiveness of conducting low accuracy rural surveys using the satellite delivered SBAS L1 Legacy Service, SBAS L1/L5 DFMC Service and SBAS Precise Point Positioning (PPP). A positioning accuracy level of 20-50cm is required in order for the new generation SBAS positioning service to meet the requirements for low accuracy rural (Class C) surveys. The new survey methods we propose here, using the SBAS technology, will be benchmarked against conventional single-baseline services provided by commercial organisations. The outcome of our project will be a feasibility analysis of whether SBAS can provide for the required accuracy needed for rural boundary surveys. The project also breaks new ground by using point data (rather than vector data) for cadastral boundary surveys.
