Otgonjargal, 50, a herdsman from Shavartai, has been using the system since last year. He said his family's income has also increased. They have more time for planting corn and making dairy products.

His parents used to graze 60 head of cattle for about nine hours a day, and now they don't have to work as hard, he added.

Chuluu, a local technical instructor for the Beidou system, said it can function in places with no signal as well. The app can count the number of steps taken by animals to prove they are in a pasture, and not just on a farm, which will help herdsmen also sell them at the higher price that range-fed beef commands.
