Abstract

In this research discusses the design circuit co-design dual-band LNA and BPF at Radio Navigation Aids (RNA) in particular equipment Very High Frequency Omni Range (VOR) / Instrument Landing System Localizer (ILS LOC) working at band working on band VHF 108-118 MHz and ILS Glide Slope (GP) on band UHF 328.6 MHz - 335.4 MHz are used for ground check monitoring. The co-design is a series of LNA and BPF are combined in a circuit. Bandpass filters are designed also serves as a substitute for the output matching impedance of the LNA, so it has the advantage of passive components becomes less and dimensions of the devices become smaller, but still have same performance with a dual-band LNA and BPF are designed in cascade by the conventional method. For comparison also designed a dual-band LNA circuit without dual band BPF and a dual band LNA and BPF in cascade. Simulation results show good performance in all curcuits. In a co-design for the center frequency of 113.0 MHz and 332.0 MHz frequencies obtained consecutive gain (S21) 24.116 dB/17.213 dB, input return loss (S11) -24.885 dB/-30.223 dB, noise figure 1.283 dB/ 1.250 dB, stability factor 1.159 / 1.778 and VSWR 1.121 dan 1.064. While the value of the measurement results of fabrication equipment and input return loss gain slightly decreased the value of simulation results but still meet the design specifications for the VHF band, UHF band but still out of tolerance from the design specifications

Abstract

B.IndonesiaRancangan program untuk memasukkan, menyimpan, dan menampilkan laporan suku cadang yang masuk ataupun yang akan keluar ini betujuan untuk meningkatkan efektifitas penggunaan dan penyimpanan suku cadang di Perum Lembaga Penyelenggara Pelayanan Navigasi Penerbangan Indonesia JATSC – Soekarno Hatta. Kondisi yang ada saat ini, teknisi mencatat suku cadang yang masuk ataupun yang akan keluar masih secara manual, yaitu pencatatan dalam tulisan tangan. Hal ini tentunya memiliki banyak sekali kekurangan, karena menyebabkan data yang tersimpan tidak rapih dan sulit untuk ditemukan. Rancangan ini merupakan aplikasi sistem database suku cadang peralatan yang yang akan digunakan untuk Fasilitas Komunikasi Penerbangan di Perum LPPNPI JATSC. Dengan adanya program database ini diharapkan teknisi akan lebih mudah dalam melakukan pencatatan dan pencarian data suku cadang karena data tersimpan dan terdata dengan baik.B.EnglishThe design of the program to inputr, save and display reports on incoming and outgoing spare parts is aimed at increasing the effectiveness of the use and storage of spare parts at the Indonesian Aviation Navigation Service Provider, JATSC-Soekarno Hatta. Current conditions, technicians record the incoming or outgoing parts are still manually, that is the recording in handwriting. This certainly has a lot of shortcomings, because it causes the data stored is not neat and difficult to find. This design is an application system database of equipment parts which will be used for Aviation Communication Facilities at Perum LPPNPI JATSC. With this database program it is expected that technicians will be easier to record and search for spare parts data because the data is stored and recorded properly

Abstract

Telecommunications technology is currently developing leading to Internet-based technology, for example the Internet Protocol. Voice Over Internet Protocol (VoIP) is a user that routes messaging, voice, and video services to an Internet Protocol network and connects to the network IP. Benefits, bandwidth efficiency, cost management efficiency.The purpose of this design is for Ground to Ground communication media at Pasir Pengaraian Airport, which does not yet have a Ground to Ground communication medium, only uses a mobile phone via Whatsapp which does not yet have an automatic record in the application, with a client application design where this application is equipped with VoIP-based telephone services. and also records of Ground to Ground communication conversations can be a Ground to Ground communication medium at Pasir Pengaraian Airport, with a simple design and relatively efficient cost, VoIP-based communication can be an alternative communication for all airports in Indonesia, Therefore the author makes VoIP communication design based on Raspberry Pi as a server using the Asterisk operating system and the client using an application designed with Android Studio configured with a Raspberry Pi server, using this client-server interconnection

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

Aviation radio communication services between Air Traffic Control and pilots must be maintained in good condition without interruption because flight safety is the main priority. The goal of the research is to reduce unwanted frequency harmonics generated from the transmitter so that the effect of frequency interference on adjacent channels can be reduced. This tool will only miss the expected frequency. This bandpass filter is set up carefully to be able used in the VHF Air Ground Communication frequency range, namely 118 – 137 MHz with a tunable combline model which has high selectivity in the frequency channel used. This research method is the design and analysis of a tool consisting of several cylindrical rod transmission lines (slabline) connected to ground at one end and a variable capacitor attached along with ground at the other end. The simulation results and measurements of insertion loss (S21) and return loss (S11) parameters still meet design standards in all VHF A/G frequency ranges. Equipment performance was tested with a working frequency of 120.0 MHz on VHF AG radio transmitter equipment Brand Icom A-120 with a power of 9 Watts, Brand Rohde & Swarch SU4200 with a power of 5 Watts, and Dittel FSG-2T with an output power of 3 Watts. Test results using the equipment can still be used with VSWR results still less than 2 and a decrease in power output of less than 20% of the nominal power.
