Passive ranging relying on broadcast signalling is very attractive in terms of scalability, and allows to provide passive ranging capabilities to billions of users worldwide with medium earth orbit satellites. Passive ranging rely on the fundamental assumption that the observed propagation delay relates to the geometric range.To enhance resilience to spoofing of the positioning-navigation-timing (PNT) services, it appears attractive to implement 2-way communication and ranging systems to introduce secure bootstrapping and waypointing. Unfortunately, 2-way communications faces multiple-access limitations as the system must interact with each user. Wireless Local Area Network and Ultra-Wideband provide 2-way ranging but in very limited coverage, while 4G Long Term Evolution only offers passive ranging signal. The introduction of a satellite component hybridized with terrestrial systems should be explored to support two-way ranging available globally.This activity encompasses the following tasks- Gather state-of-the-art and emerging technologies- Identify, design and develop the innovative techniques- Assess their performances- Synthesis and recommend ways forward
