      An ultrasonic sensor is a device that works in much the same way as RADAR and SONAR. In fact, ultrasonic sensors mimic bats and other animals’ natural ability to use ultrasonic frequencies for navigation. Ultrasonic sensors broadcast a powerful, ultrasonic frequency, then detect the ultrasonic sound waves as they bounce off of objects and return

      SCPC (Single Channel Per Carrier)

      SCPC stands for Single Channel Per Carrier. SCPC is a form of satellite transmission where each channel is transmitted on a dedicated single carrier. The alternative to SCPC is MCPC (Multiple Channel Per Carrier). MCPC is more efficient than SCPC, but SCPC is still utilized for some satellite feeds. By using SCPC, satellite users are
