081 - Lithium Niobate Photonic integrated circuit based high speed, low voltage modulators for microwave photonics
Recent advances in both the development and heterogeneous integration of Lithium Niobate (LiNbO3) on Silicon Nitride for high-speed modulators have brough with it the possibility to combine several functionalities on a compliant heterogeneous platform. In the progress towards higher efficiencies, a reduction in system complexity and enhanced reliability for system critical applications such as…
076 - Low SWAP optical clock control unit
The need for high-accuracy, resilient holdover techniques to be available in the event of GNSS signal denial has been widely emphasised. Whilst current microwave GNSS satellite clocks, and best-in-class commercial microwave clocks, provide holdover for relatively short periods in situations where GNSS system disciplining is lost, it is clear that future resilient PNT systems will need to maintain…
072 - Navigation Using Machine Learning Applied to Signals of Opportunity
There is an existing need to optimise navigation in challenging environments, such as deep urban or indoor, and to offer alternative PNT. For this purpose, the user may complement the GNSS with space-based (e.g. LEO SatCom) or terrestrial-based (e.g. cellular) signals of opportunity (SOOP) to optimise the PNT performance. SOOP could also be exploited similarly in a maritime…
067 - Precision Agriculture - High precision coordinate and alignments transfer
In future precision agriculture, it is expected that each plant (e.g. corn) will get coordinates with very high accuracy. The type of plants and their coordinates will be stored in a database with additional agricultural information. Therefore, already during the sowing process each finger of the seeder comb/seed drill has to be coordinated with high accuracy in the relevant navigation reference…
059 - Application of photonics technology for PNT user equipment
The demand for seamless positioning of IoT devices both outdoors and indoors is an important requirement for many logistic applications relevant to the digital transformation of industry. This is becoming more relevant as the degree of automation in industrial operations increases, together with the need of permanently tracking the location of inputs from suppliers, to be able to forecast…
