Radio Navigation: Perspectives and Challenges
Society, including many European governments, has a strong belief in the reliability of today’s primary radio navigation system, GPS. Unfortunately, space-based as well as terrestrial-based systems have some serious limitations that cannot be ignored if continuity of service plays a keyrole in the process in which these systems are used. The paper indicates some weaknesses of radio navigation s...
متن کاملNavigation Sensor Accuracy
The paper draws attention to the emerging military capabilities of laser radar by describing state-oftechnology sensor processing results for applications involving helicopter obstacle warning, automatic target identification at far range and automatic target detection and classification at close range. In all applications sensor processing requires accurate motion compensation using navigation...
متن کاملThe ionosphere , radio navigation , and global navigation satellite systems
This article is a review of Global Navigation Satellite Systems for space scientists who are interested in how GNSS signals and observables can be used to understand ionospheric dynamics and, conversely, how ionospheric dynamics affect the operational capabilities of GPS. The most common form of GNSS is the Global Positioning System (GPS); we will first review its operating principles and then ...
متن کاملFlight Test Result for the Ground-Based Radio Navigation System Sensor with an Unmanned Air Vehicle
The Ground-based Radio Navigation System (GRNS) is an alternative/backup navigation system based on time synchronized pseudolites. It has been studied for some years due to the potential vulnerability issue of satellite navigation systems (e.g., GPS or Galileo). In the framework of our study, a periodic pulsed sequence was used instead of the randomized pulse sequence recommended as the RTCM (r...
متن کاملRadio-frequency sensor fusion for relative navigation of formation flying satellites
The increasing need for robustness, reliability and flexibility of relative navigation systems imposed by the current and future autonomous formation flying missions, calls for the implementation of solutions using an alternative approach to single-sensor systems. These schemes possess different levels of availability, mainly driven by sensor failure and mission orbit profiles. The data obtaine...
