This document reviews the characteristics of navigation system technology in the context of the Johan Sverdrup facility, the available navigation infrastructure and the desired operations therein. After discussing the benefits and drawbacks of the foreseeable sources of navigation data, the feasibil...

This paper discusses design details and field test verification results of a low-cost Radio Frequency Interference (RFI) event logger developed for monitoring the Global Navigation Satellite System (GNSS) L1 and L5 frequency bands for anomalous emissions that might disrupt or degrade Ground Based Au...

This paper investigates the challenges of developing a multi-frequency radio frequency interference (RFI) monitoring and characterization system that is optimized for ease of deployment and operation as well as low per unit cost. To achieve this, we explore the design and development of a multiband ...

It is common knowledge in the GNSS community that the ionosphere is dispersive in the L-band, meaning the refractive effects on the carrier phases are proportional to the wavelengths of the carriers, in turn causing differential variation in the measured codes and phases of the various navigation si...

A time-multiplexing approach to multi-frequency receiver operation is introduced in this paper, wherein a single-frequency receiver platform is configured to dynamically re-tune to each of a selection of different carrier frequencies to produce multi-frequency measurements. The development of a prot...
