Abstract

The increasing complexity of electrical and electronic systems in unmanned aerial vehicles (UAVs) has raised concerns regarding unwanted electromagnetic interference (EMI) due to limited compartment space. Recent studies have highlighted the UAV cabling as the primary pathway for interference. This paper presents a novel approach to investigating the effects of interference power, polarization angle, and distance from the interference source on EMI in UAV cable systems. Measurements and simulations were performed to analyze the influence of these factors on the radiation received by the cable. A linear dipole antenna, operating at a frequency of 905 MHz, served as the radiation source, while a single wire cable pair terminated with a 50-ohm resistor was employed as the victim. The findings reveal that the power transmitted by the source, the distance between the cable and the source, and the polarization angle have a significant impact on the electromagnetic interference received by the cable. Notably, a perpendicular orientation of the cable to the interference source (antenna) in the far-field yielded a reduction of up to 15 dBm in EMI. The results underscore the necessity for more sophisticated models and comprehensive measurements to fully comprehend the diverse factors affecting polarization losses in practical scenarios.

Abstract

Limited QCIs (QoS Class Identifiers) restrict the handling different service types with varying quality requirements. This necessitates research on QoS management to minimize latency and improve user experience, particularly for real-time applications like video conferencing and online gaming. This paper proposes a combined optimization scheme targeting QCI 3 to reduce latency. The approach involves disabling DRX, optimizing pre-allocation, and reducing the PDCP discard timer. The optimization performance is studied by taking the case of an e-sport game that demands low network latency, affecting the quality of the players' experience. The optimization scheme was validated through functionality, resource allocation, and air interface latency tests conducted under actual e-sport gaming conditions. Network latency was measured every minute to evaluate the impact of optimization on esports games running under QCI 7, QCI 3, and optimized QCI 3. In addition, air interface latency for optimized QCI 3 under networks with poor coverage and very high-capacity networks was compared to latency under QCI 8 (basic), QCI 7, and regular QCI 3. The optimization strategy demonstrated a significant reduction in air interface latency, up to 19% improvement compared to non-optimized QCI 3. It has reduced air interface latency's maximum, minimum, and standard deviation values during gameplay. The strategy also ensured concurrent operation with multiple QCI values without compromising other application’s throughput. The proposed optimization strategy effectively enhances the user experience by significantly reducing average latency and jitter.

Abstract

Keselamatan penerbangan merupakan hal mutlak yang harus di wujudkan dalam penyelenggaraan layanan navigasi udara. Instrument Landing System (ILS) dan Very High Frequency Omni Range (VOR) merupakan fasilitas yang berfungsi untuk panduan arah terbang, pendekatan dan pendaratan pesawat di suatu bandar udara. Sistem ini bekerja pada pita VHF (108 – 118 MHz)  dan pita UHF (328,6 – 335,4 MHz). Pada pengujian sistem tersebut diperlukan antena yang dapat bekerja pada masing-masing frekuensi VOR dan ILS. Pada penelitian ini dilakukan perancangan antena dual band yang  mampu bekerja secara bersamaan (concurrent) pada frekuensi VOR dan ILS agar pengujian menjadi lebih efisien dan praktis dibandingkan pengujian menggunakan antena single band secara bergantian. Perancangan diawali dari perhitungan dimensi secara matematis, simulasi, fabrikasi antena, pengukuran parameter dan analisis hasil agar diperoleh rancangan antena yang memenuhi spesifikasi yang ditetapkan. Hasil analisis menunjukkan bahwa antena dapat bekerja pada pita VHF (113 MHz) dan UHF (332 MHz) dengan nilai return loss sebesar -23,82 dB  dan  -21,7 dB. Nilai VSWR didapatkan sebesar 1,137 dan 1,179 sedang nilai gain yang dihasilkan sebesar 1,74 dBi dan 2,9 dBi. Antena memenuhi parameter yang ditetapkan sehingga dapat digunakan pada pengukuran VOR dan ILS receiver.

Abstract

One of the aviation navigation tools is the Instrument Landing System (ILS), which functions to provide guidance signals to aircraft in the final approach position toward the runway. The ILS consists of three components: the Localizer, Glide Path, and Marker Beacon. To ensure aviation safety and security, navigation equipment must be regularly inspected through Ground Inspection. With current technological advancements, Ground Inspection is being conducted using UAVs or drones. One of the components to be installed on the UAV is the PIR, which requires two antennas of different lengths to receive signals from the Localizer and Glide Path.In this study, a dual-band antenna was developed that combines a dipole antenna and a meander line microstrip antenna for frequencies 108-112 MHz and 328.6-335.4 MHz, using CST Studio Suite 2021 software and FR-4 substrate material. Simulation results showed good performance with a return loss value of -19.43471 dB, VSWR of 1.238951, and a bandwidth of 2 MHz at a frequency of 110.5 MHz, and a return loss value of -27.41626 dB, VSWR of 1.119686, and a bandwidth of 2.5 MHz at a frequency of 329.6 MHz.Measurement parameter values for the VHF band were a return loss of -14.1680 dB, VSWR of 1.487, and a bandwidth of 14.6 MHz. Meanwhile, for the UHF band, there was a shift in the resonance frequency to 368.5 MHz with a return loss value of -15.4202 dB, VSWR of 1.408, and a bandwidth of 11.4 MHz. In this antenna design, a dual-band combination of a dipole and a meander line microstrip antenna with dimensions of 320 mm was achieved, capable of operating in both the VHF and UHF frequency bands simultaneously. However, this antenna can only operate at the Localizer working frequency.

Abstract

Precision landing guidance is critical for aircraft safety, yet recurring signal anomalies in the ILS Glide Path on runway 24 at the Jakarta Air Traffic Service Center raise concerns about approach and landing reliability. Despite compliance with standard regulations, persistent signal anomalies affecting glide slope accuracy raise concerns about safe aircraft approach. This study investigates the sources of distortion, quantifies their impact on ILS Glide Path performance, and proposes mitigation strategies. Spectrum analysis, environmental assessments, and signal evaluation through oscilloscopes and navigation analyzers were employs to identify and quantify sources of distortion. Results indicate that while composite audio signals comply with standards, navigation analyzer readings reveal persistent deviations in Difference in Depth of Modulation (DDM) due to harmonic distortions at 30 Hz and its multiples up to 450 Hz. These distortions could interfere with DDM values received by calibration aircraft, making conventional technical adjustments, such as power level settings and antenna reconfigurations, insufficient for complete resolution. Instead, alternative mitigation approaches including reducing environmental reflections, optimizing siting criteria, and refining regulatory compliance measures are recommended. These findings provide valuable insights for enhancing ILS Glide Path reliability, refining signal mitigation strategies, and ensuring regulatory compliance for safer aviation navigation systems.
