ESA's NAVISP Invitations to Tender invitations to tender from NAVISPTue, 07 Dec 2021 10:42:17 +0000048 - User Antenna Diversity for efficient multipath mitigation impact of multipath and fading in harsh propagation conditions is still among the main sources of errors in PNT solutions for mobile users. Besides code-based positioning accuracy, they affect convergence time of carrier-based solutions (e.g. PPP) and may prevent ambiguity resolution. For handheld user equipment (HH-UE) such as smartphones and tablets, antenna performance is traded against…Tue, 07 Dec 2021 10:42:17 +0000latest-ittsitt-70054 - Monitoring timing signals from space. A novel approach for a worldwide robust time and synchronisation capability systems (including critical infrastructure) rely on GNSS receivers for synchronization purposes nowadays, for instance telecom networks, power grids and financial markets. Due to the vulnerability of GNSS to interference and spoofing, there is a growing need on alternative (non-GNSS-dependent) timing services, as shown by several investigations and initiatives on this topic (e.g. European…Tue, 07 Dec 2021 10:40:47 +0000latest-ittsitt-76061 - Navigation payload demonstrator of future LCNS satellites exploration is emerging as the next global strategic priority in space exploration. Several dozens of commercial and institutional missions to the Moon are planned for the coming decades, with a major contribution also expected from ESA (e.g. Orion service module, ESA participation in Gateway lunar station and contribution to multiple lunar robotic missions). In spite of the wide variety of…Fri, 26 Nov 2021 12:28:02 +0000latest-ittsitt-83056 - Advanced algorithms and techniques for resilient time provision trends show a clear increase in number of timing-dependent services (including highly critical ones), with increasing demand for improved performance and capability. RF signals broadcasting is becoming increasingly dependent on GNSS for accurate timing and frequency references. 5G networks will be increasingly dependent on precise and robust timing and synchronisation.

Trusted PNT solutions have to be developed to help tackle the many challenges that a congested airspace brings such as the safety of…Tue, 30 Mar 2021 10:19:20 +0000latest-ittsitt-74055 - Attitude control of autonomous ships navigating in ports of the many new emerging concepts having the potential to address present and future maritime challenges is autonomous ship navigation. In particular, the concept is expected to allow for more efficient and competitive ship operations while reducing, at the same time, vessels’ environmental impact. Several activities have been initiated in the recent years with the aim to jumpstart the…Tue, 30 Mar 2021 10:18:10 +0000latest-ittsitt-77057 - Development of advanced VDES-R user technologies for alternative PNT (VHF Data Exchange System) aims at digitalising maritime communications and enable the introduction of new capabilities for a variety of maritime use cases, such as AIS and Search and Rescue. It is also being considered to support alternative PNT with a dedicated ranging capability, the so-called R-mode or VDES-R, which is currently being investigated.
