Quality of Service (QoS) Analysis for Real-Time Telemetry By IP Satellite Communication

This paper presents the Quality of Service (QoS) analysis for real-time telemetry by Internet Protocol (IP) satellite communication for LAPAN Surveillance UAV (LSU) platform. The satellite communication system is one of the communication systems that provide a broadband of communication space. Hence, Aeronautic Technology Center of National Institute of Aeronautics and Space (Pustekbang-LAPAN) proposed real-time communication UAV by using satellite as its repeater. The topic to be discussed in this paper is the reliability of an IP-based modem that is defined as the quality of service (QoS). QoS parameters used for data transfer performance analysis are packet loss, delay, and jitter. The communication protocol used in this test is User Datagram Protocol (UDP) with Virtual Private Network (VPN) and without VPN. Data obtained using network traffic monitor named Wireshark. From the results of data analysis, packet loss data on the UDP protocol with VPN is 1.96% with an average delay of 1.12 seconds while for UDP packet loss protocol without VPN is 4.56% with a delay of 0.96. In terms of communication channel reliability, it is found that the use of UDP with VPN is better in QoS.
