نویسندگان
چکیده
The scope of D1.4 Gap Analysis of GNSS Receivers and Technology is to review the state-of-the-art for mass market receivers for the mobile terminal market, review the state-of-the-art for high-end Global Navigation Satellite System (GNSS) receivers and identify technology gaps that exist. Given the investigations in D1.1 Market Definition and Core Technology Report on key core technological drivers and key core technologies as well as the review of state-of-the-art mass market receivers for the mobile terminal market in Chapter 1 and high-end GNSS receivers in Chapter 3 of this deliverable, the major technology gaps have been identified.

A Concurrent Dual-Band Low Noise Amplifier for GNSS Receivers
In this paper, a new design of concurrent dual-band Low Noise Amplifier (LNA) for multi-band single-channel Global Navigation Satellite System (GNSS) receivers is proposed. This new structure is able to operate concurrently at frequency of 1.2 and 1.57 GHz. Parallel and series resonance parts are employed in the input matching in order to achieve concurrent performance. With respect to used pse...
متن کاملEvaluation of Geometric and Atmospheric Doppler for GNSS-RO Payloads
To reduce the sampling rate in global navigation satellite system (GNSS)-radio occultation receivers, it is essential to establish a suitable estimation of Doppler frequency from the received signal in the satellite onboard receiver. This receiver is usually located on low earth orbit satellite and receives GNSS satellites signal in the occultation situation. The occurred Doppler on the signal ...
متن کاملA Novel Sampling Approach in GNSS-RO Receivers with Open Loop Tracking Method
Propagation of radio occultation (RO) signals through the lower troposphere results in high phase acceleration and low signal to noise ratio signal. The excess Doppler estimation accuracy in lower troposphere is very important in receiving RO signals which can be estimated by sliding window spectral analysis. To do this, various frequency estimation methods such as MUSIC and ESPRIT can be adopt...
متن کاملDerivation of the Cramér-Rao Bound in the GNSS-Reflectometry Context for Static, Ground-Based Receivers in Scenarios with Coherent Reflection
The use of the reflected Global Navigation Satellite Systems' (GNSS) signals in Earth observation applications, referred to as GNSS reflectometry (GNSS-R), has been already studied for more than two decades. However, the estimation precision that can be achieved by GNSS-R sensors in some particular scenarios is still not fully understood yet. In an effort to partially fill this gap, in this pap...
متن کاملLgsp: a Lightweight Gnss Support Protocol for Military and Civil Applications
We present a Lightweight GNSS (Global Navigation Satellite System) Support Protocol (LGSP), which has been devised at Monash University. LGSP aims to comprehensively address limitations in the traditional GNSS model, such as low signal availability in urban environments, receiver initialisation delays and bandwidth restrictions, by offering an alternative secure distribution channel for GNSS da...
