STERNA System accurately finds True North in virtually all terrains and regardless of the weather conditions. The performance of STERNA System is not disturbed by gear carried by its operator or if used next to heavy armored vehicles. It remains highly accurate even when deployed on reinforced concrete floors or in dense urban settings. STERNA System operates reliably even in GPS denied environments and does not require the operator to carry any support resources to determine True North. If your mission success depends on the highest level of accuracy and precision, there is no substitute for STERNA System.
