The manufacture of expensive and complex communication satellites need to be thoroughly inspection with videoscopes. Any potential defect or foreign debris needs to be discovered for a space satellite to function properly. A videoscope can be snaked through tubes and behind electronic panels to check for problems before the construction is completed. Typically it is impossible to reach inside these small accesses to visually inspect for problems. Videoscopes are small enough to snake behind panels or be pushed through tubes as small as 4.0mm and as long as 50 ft.
Without videoscope inspection of these critical areas defect may go unnoticed and foreign debris may be inadvertently left inside the critical components of the satellite. A small defect such as a hairline crack could easily cause system failure. Foreign debris such as a small tie wrap needs to be removed or the object may "float" in zero gravity and cause a short between electronic components. Videoscopes are available in a range of length, diameters and directions of view to meet multiple applications.
Before a satellite is packed and launched into space manufacturers ensure that they have completed a thorough remote visual inspection of the entire system using the most modern videoscopes available.
