“…The mobility of NGSO satellite brings about a variable receive power at the ground terminals, which is then represented as a function of the ground antenna elevation and the slant path through the atmosphere [102]. Besides, the high mobility of NGSO satellites causes the well-known Doppler phenomenon and its potential impact on communication links.…”

The next phase of satellite technology is being characterized by a new evolution in non-geostationary orbit (NGSO) satellites, which conveys exciting new communication capabilities to provide non-terrestrial connectivity solutions and to support a wide range of digital technologies from various industries. NGSO communication systems are known for a number of key features such as lower propagation delay, smaller size, and lower signal losses in comparison to the conventional geostationary orbit (GSO) satellites, which can potentially enable latency-critical applications to be provided through satellites. NGSO promises a substantial boost in communication speed and energy efficiency, and thus, tackling the main inhibiting factors of commercializing GSO satellites for broader utilization. The promised improvements of NGSO systems have motivated this paper to provide a comprehensive survey of the state-of-theart NGSO research focusing on the communication prospects, including physical layer and radio access technologies along with the networking aspects and the overall system features and architectures. Beyond this, there are still many NGSO deployment challenges to be addressed to ensure seamless integration not only with GSO systems but also with terrestrial networks. These unprecedented challenges are also discussed in this paper, including coexistence with GSO systems in terms of spectrum access and regulatory issues, satellite constellation and architecture designs, resource management problems, and user equipment requirements. Finally, we outline a set of innovative research directions and new opportunities for future NGSO research.

“…The EIVE CubeSat is a technology demonstration mission with the main payload being an 71-76 E-band transmitter with an analog bandwidth of up to 5 GHz and a maximum data rate of up to 10 Gbit s −1 depending on the modulation format [3]. The objective of the E-band transmitter payload is to investigate the radio link quality with multiple signal modulations under different conditions like weather, slant range and elevation above the horizon [4,5].…”

The 6 Unit CubeSat EIVE was developed to to host a novel high-speed E-band transmitter payload. Challenging aspects for reliable and demanding satellite architectures were revealed during development and operations. Reliable communication buses such as CAN, RS485 or point-to-point links should be preferred over I2C or SPI. Experiences from the implementation of the individual subsystems are presented and lessons learned derived in this paper. The on-board data handling and communication system is based on a system-on-a-chip architecture and uses the CCSDS protocol via S-band. The FPGA section proved advantageous while the use of high-priority commands is essential for in-orbit debugging. The conservative approach to the design of the power system and the high effort to test the thermal design of the EIVE CubeSat led to a stable satellite regarding the power-budget and temperature ranges. The self-developed solar panels and their deployment mechanism worked as intended with many lessons learned in the process. A major part of the time spent on integration was on the harness. The attitude control system is based on self-developed components and commercially acquired units. With most of the attitude control components being tested and calibrated on a best effort basis, more resources should have been committed to testing the GNSS receivers and the star tracker on ground. A stable safe mode was achieved after multiple bugs fixes in the first weeks after the launch. Since then, steady progress towards nominal operation has been achieved.

“…Modern trends in miniaturisation and demands for higher resolution have prompted radar technologies to explore and utilise W-band frequencies, i.e. 75-110 GHz, to exploit the higher available bandwidth [1], [2]. Moreover, due to low atmospheric losses W-band frequencies provide better Signalto-Noise ratio (SNR) than the previously used frequency bands at around 24 GHz and 60 GHz.…”

In this paper, a planar spiral resonator operating at 13 GHz is investigated. The resonator was fabricated using fan-out wafer level packaging (FoWLP) technology. The field analysis highlights the importance of via fence. Two thick film resistors suppress an undesired resonance in proximity of targeted one. The measurements demonstrate a very good correlation in comparison with full-wave simulations. The measured Q-factor defined based on analysis of feedback oscillatory system is about 48. The proposed configuration is suitable for voltage-controlled oscillators (VCOs) with a resonator realized in package.
