This paper aims to provide navigation system designers with a detailed examination of the impact of inertial measurement unit (IMU) rotation on error reduction or induction in a rotary inertial navigation system (INS). The designer of a rotary INS can select the optimal rotation rate and direction by considering the dynamics of the carrier and the dominant errors based on the findings reported in three concise tables within this paper. This paper presents a comprehensive analytical derivation of error equations for the attitude, velocity, and position of a rotational INS, validated through numerical simulations. Experiments using a rotation platform and actual data from a micro-electromechanical system IMU sensor are also conducted to verify the effectiveness of mitigating errors through IMU rotation. Moreover, a tensor-based modeling technique is employed to facilitate exploring the impact of IMU rotation around an arbitrary axis on accumulated errors. This approach provides a modular platform for further research on rotational navigation systems.

We’re excited to host Dr. Ciro Gioia from the European Commission, Joint Research Centre, for a deep dive into his technical paper, "Galileo High Accuracy Service: Tests in Different Operational Conditions." Join us for this complimentary webinar on Wednesday, March 26 at 12:00 p.m. EDT: info.ion.org/webinar ?? About the Paper/webinar: The Galileo High Accuracy Service (HAS) provides real-time precise point positioning (PPP) using corrections transmitted via the E6 signal. Once fully operational, HAS aims to deliver 20 cm horizontal and 40 cm vertical accuracy (95% confidence level). This webinar will present the latest findings from tests conducted in both static and dynamic environments, including open-sky and urban canyon scenarios. Results demonstrate that HAS corrections significantly improve positioning accuracy, with signal-in-space corrections available ~95% of the time in dynamic tests. ??

The very-high-frequency data exchange system (VDES) is an emerging maritime radio communication system that will pave the road for novel e-navigation applications. A key problem in e-navigation is that of data authentication: determining that the data originate from a trusted party and have not undergone changes after transmission. This work considers the authentication requirements in VDES, while considering the constraints typical of the maritime environment, and analyzes several possible solutions. The proposed solution is two-tiered, with the default approach relying on digital signatures in low-traffic areas where available wireless capacity is sufficient. For areas under the control of a shore station for which available wireless capacity is low, we consider a low-overhead authentication scheme using the timed efficient stream loss-tolerant authentication (TESLA) protocol to authenticate all shore-to-ship traffic. TESLA is particularly attractive for future-proof quantum-safe cryptography, offering increased authentication data under the conditions of the low-data-rate VDES.

The concept of observing pulsars for space autonomous navigation has already caught the attention of space agencies. Driven by the extremely stable nature of pulsar radiation, many research works and in-orbit demonstrations have been performed, demonstrating the suitability of these sources for navigation. The core concepts of the in-orbit demonstrated X-ray pulsar-based navigation systems and the recently proposed space navigation by optical pulsars (SNOP) systems are based on the capability to accurately define the arrival times of a pulsar signal. Therefore, the performance of a pulsar-based navigation system depends on the timing accuracy of the measured signals, which is a function of the characteristics of the navigation payload onboard the satellite. The aim of this paper is to investigate the impact of the optical parameters of a photometer-based instrument on the timing accuracy of a SNOP system; moreover, a first optical design for the payload is proposed.
