Abstract

Receiver Autonomous Integrity Monitoring (RAIM) is a method to monitor the integrity of GPS using mesurement to redundant satellites on the receiver side. Comonly 2 algorithm are used to perform RAIM, i.e. snapshot method and sequential method. In snapshot method, single set measurement of GPS signal is used, meanwhile in sequential method several sets of measurements (past and current) GPS signal are used. Therefore, the sequential method has the capacity to detect position failure due to low fault to noise ratio. The low fault to noise ratio is mostly caused by the satellite’s position at the time of position measurement. RAIM is very useful for GPS users to be able to determine the whether the GPS can give accurate position, based on its satellite’s positions, satellite’s service life or error in the receivers. Such accuracy is important especially for the use in GPS navigation sistem in Air Traffic Management (ATM). The disturbance can also be caused by ionosfer condition. In order to support the use of GPS navigation system in ATM in Indonesia, Communication Navigation Surveillance-ATM (GPS CNS-ATM) team of BPPT perform simply RAIM asessment that can be informed to the flightcrew or Air Traffic Center, to be informed via Notice To Air Men (NOTAM). The GPS signal observation is done in 5 different locations in Indonesia. Keywords: Air navigation system, GPS

Abstract

Sistem Telemedicine terdistribusi yang dikembangkan Pusat Teknologi Elektronika-Badan Pengkajian dan Penerapan Teknologi (PTE-BPPT) mempunyai bagian yang dinamakan Telemedicine workstation, dilengkapi dengan modul Vital Sign dan modul pemeriksa gula darah Noninvasive. Modul Vital Sign digunakan untuk mendapatkan data medis tekanan darah, kadar oksigen dalam darah, suhu tubuh dan sinyal EKG. Modul pemeriksa gula darah Noninvasive menggunakan infra merah untuk memeriksa kadar gula darah pada pasien. Penambahan modul Vital Sign dan modul pemeriksa gula darah pada Telemedicine workstation dapat digunakan sebagai data pendukung dokter puskesmas saat berkonsultasi dengan dokter spesialis di rumah sakit.

Abstract

Telemedicine workstation yang telah dikembangkan Pusat Teknologi Elektronika Badan Pengkajian dan Penerapan Teknologi (PTE-BPPT) dapat digunakan oleh dokter umum yang ada di Puskesmas. Perangkat ini dilengkapi dengan peringatan abnormalitas tanda-tanda vital. Modul tanda-tanda vital digunakan untuk mendapatkan data suhu tubuh, denyut nadi, laju pernapasan, saturasi oksigen, dan tekanan darah. Peringatan abnormalitas tand-tanda vital dapat digunakan sebagai pengingat dokter akan adanya ketidaknormalan pada tanda vital pasien. Sehingga dengan adanya peringatan abnormalitas dapat mempercepat pengambilan keputusan oleh dokter.

Abstract

A-SMGCS is an airport system that is used to improve the efficiency of using runways, apron and taxiways by maximizing runway capacities in all situations and weather while maintaining the required level of security. One of the parameters that becomes a requirement in the A-SMGCS system is the Probabillity of Target Report (PTR) whose value must be greater or equal to 95% in the area maneuver with update rate of the data one second [1]. Automatic Dependent SurveillanceBroadcast (ADS-B) is one of the cooperative sensors in the A-SMGCS system. The ADS-B sensor is a receiver that is used to capture ADS-B data from aircraft or vehicles equipped with ADS-B transmitters. The amount of ADSB data received by the ADS-B receiver and is needed for the A-SMGCS system is one of the factors that determine the Probability of Target Report (PTR). This paper will test three ADS-B receivers which will be selected for use as a cooperative sensor in the next A-SMGCS development. From the results of analysis and retrieval of data obtained by Radarcape ADS-B receiver more suitable for the development of the A-SMGCS system.
