Delivering products to the IGS community

The role will be based in Canberra ACT, Australia in Geoscience Australia (GA), Geodesy section within the small project team and report to the project´s Technical Leader (TL).

Responsibilities include:

-         
Software development, maintenance, testing, debugging, prototyping based on technical requirements, standards and design provided by the TL

-         
Implement dynamic POD models for the generation of real-time, rapid and weekly final multi-GNSS orbits and clocks

-         
Implement un-differenced or single and double differenced algorithms of multi-GNSS (GPS, GALILEO, GLONASS, BEIDOU, QZSS, IRNSS), un-combined or combined multi-frequency data.

-         
Implement multi-GNSS, multi-frequency data editing and cleaning algorithms (cycle slips, clock jumps etc.) both in real-time and post-processing

-         
Implement, verify and control the GNSS signal in space specifications and GNSS system performance standards

-         
Implement, verify and control the International Earth Rotation Service (IERS 2010) conventions, and the IGS Repro 2 campaign standards

-         
Teamwork, Coordination and Technology transfer providing technical expertise and advice within the project in the area of GNSS and satellite positioning techniques

-         
Perform research work and publish in International peer-reviewed journals as requested

Minimum requirements :
