usals

usals stands for Universal Satcom Alignment System. It is a set of commands and protocols designed to automate the aiming of satellite dishes. Developed by a German hobbyist named Martin Lötzsch, usals allows a satellite receiver to instruct a motor attached to a satellite dish to move to the correct azimuth and elevation for a desired satellite. This eliminates the need for manual adjustment of the dish for each satellite, providing a seamless user experience when accessing multiple orbital positions.

The system works by sending precise motor control commands from the satellite receiver to the dish motor. These commands are based on the calculated position of the satellite in the sky relative to the user's geographical location. When a user selects a channel from a different satellite, the receiver interprets this and sends the appropriate usals commands to the motor. The motor then adjusts the dish's position to lock onto the new satellite.

usals is widely supported by many satellite receivers and dish motors, making it a popular choice for those with motorized satellite dish setups. It simplifies the process of satellite tracking, allowing users to easily access a wide range of satellite television and radio services without requiring technical expertise in dish alignment. The system's effectiveness relies on accurate geographical data input into the receiver and compatibility between the receiver and the motor.
