A system utilizes two ground-based radios; each radio is equipped for two-way timing and ranging. An aerial vehicle receives radio signals from the two ground-based radios and triangulates its location with respect to those two ground-based radios. The aerial vehicle then executes a landing procedure at a landing site with respect to the triangulated location. The aerial vehicle includes a barometer, radar, or laser altimeter for vertical measurement. The aerial vehicle also includes an inertial measurement unit (IMU), air data system, and magnetometer. The ground-based radios may supply a ground level altitude measurement. The aerial vehicle may perform an acquisition orbit for improved accuracy. The acquisition orbit provides an expanded range of geometries with respect to the two ground-based radios.
