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.

Multilateration (MLAT) is a technology used to determine the position of an object by using a Time Difference of Arrival (TDOA). MLAT is used at airports as one of the sensors in the A-SMGCS system to determine the position of an aircraft or vehicle. Developing an MLAT system should ideally be done at the airport because it requires aircraft and vehicle objects that are already equipped with ADS-B transmitters, but developing an MLAT system at the airport requires high costs for equipment installation and licensing because it risks disrupting airport operations and can disrupt existing systems . The Center of Technology for Electronics - BPPT is developing the A-SMGCS system and is based in the serpong puspiptek area, where this area has a large enough area, making it possible to design prototypes of the MLAT system. Three ADS-B receivers are placed in three different buildings that are still connected to a computer network, so that data collection from each receiver can be done through the BPPT local network. The object to be calculated is using a car equipped with an ADS-B transmitter. To get more accurate results, every time the receiver is synchronized using GPS. The experimental results show that there is a difference between the position data sent by the ADS-B transmitter and the results of the MLAT calculation, this is due to the difference in height of the three receivers, accuracy of GPS and accuracy of the ADS-B receiver timestamp used. Although there are differences, the proof of concept design of this system is in accordance with the characteristics of the MLAT system. The benefit gained from the design of this prototype is that it can develop an MLAT system in a place that is not high risk with low cost but the results can be applied at the airport.
