1. MICROSAT - ON THE MOVE TERMINAL 1.1 GENERAL SYSTEM INTRODUCTION The MicroSAT is a lightweight portable “on-the-move” satellite terminal solution. It is designed for compact installation, and fully autonomous operation for transmit and receive of high bandwidth data. The system is utilizing an innovative high performance panel antenna, with a full control over elevation and azimuth to allow automatic operation for the position and tracking. This results in a low-weight / low profile antenna with superior stiffness and high performance to support multiple applications requiring “On-The-Move” communications. The system was designed according to FCC 225, MIL STD 461. GETSAT communications LTD. is ISO9001 certified. 1.2 MICROSAT MAIN FEATURES  Aluminum Gimbal  Lightweight  Low profile  Modem / Data-link agnostic  GPS / Compass  High Accuracy Pointing  Easy Integration to any platform  Scalable (Different Antennas)  Low power consumption  Plug & Play operation after pre configuration 2 Business sensitive

2.1.8 OPERATION MODES Manual mode controls the antenna in each direction from ICD (RS232/IP). AZ Step Resolution = 0.1 deg Manual EL Step Resolution = 0.1 deg Az = 0, El = 0 points to Home Motor ctrl = Encoder loop PID This Mode is based on AZ/EL IMU. The system closes the pointing loop using angles from the static IMU on Euler the Base of the unit. Angles This mode usually initiated during power up and search mode sequence for initial pointing position. This Mode based on El IMU. The system close the Loop with 3-Axis Gyros from rotating head. During this mode the system perform the correction of the Gyro pointing using the RSSI and the Gyro's installed on the Tracking antenna. Using the Multi feedback mechanism (RSSI and IMU) the system can perform the excellent pointing to the base station without GPS. FIGURE 8: SYSTEM OPERATION MODES 12 Business sensitive
