CM501G is a Chinese land attack missile first revealed during the 9th Zhuhai Airshow held in November 2012.
CM-501G also has more guidance options such as Satellite/INS, imaging infrared (IIR), semi-active laser homing (SAL) and in-flight updates for re-targeting if needed.
The developer has claimed that the open architecture and modular design concept made the CM-501G system versatile enough to meet different financial constraints customers face by selecting different guidance systems: when budgetary constraints limit the funding, the two way data link and IIR can be replaced by cheaper SAL, and satellite guidance can be any of GPS, GLONASS, or BeiDou.
[2] The basic CM-501G system consists of two vehicles both based on a Shaanxi Automobile Group SX2190 6 x 6 cross-country heavy-duty truck.
When a human operator is in the loop for re-targeting after receiving the update via a two-way data link, this task is completed in the command vehicle.
