An infrared laser landing marker system provides a capability to mark a boundary line of varying lengths with near infrared lasers, e.g., of the order 8xx nm. This system can be either directly operated or remotely operated via satellite communications and is compatible with currently fielded night vision goggles. Two modules, placed at either end of boundary, self align to each other and then proceed to mark a boundary edge of a landing zone with an infrared laser line.
