Global study: seamless carbon accounting for cross-border parcels-This call for tenders concerns the provision of consultancy services to the UPU for the development and con-duct of a study and report tentatively entitled “Global study: seamless carbon accounting for cross-border parcels”. This initiative is a response to growing demand from postal stakeholders – including major e‑commerce providers – for accurate estimates of the end-to-end greenhouse gas emissions associated with sending a single cross-border (international) parcel.

Fused PNT Analyses based on European Infrastructure - The European Commission is launching a study on the potential use of communication-oriented LEO constellations for the deployment of a complementary PNT service. This approach is normally referred to as Fused PNT. This tender will focus on developing a user terminal prototype and a simulated environment enabling to assess the performance of Fused PNT under a realistic set of propagation conditions and inter-satellite interference. In this procurement, the main goals of the European Commission are: - To develop a software receiver, supporting acquisition and tracking of 3GPP reference signals for Non-terrestrial networks (NTN) - To model multipath channel and intersatellite interference, in order to test the software receiver under the realistic satellite based propagation channel and interferences; - To consolidate and complement the part of the E2E emulator, by adding multipath and intersatellite interference models; - To demonstrate the performance of fused PNT ranging in a representative simulated environment - To validate the acquisition and tracking performance in realistic environment.
