Abstract
A circuit arrangement is provided for processing satellite signals comprising a first circuit part, which is made as a processor for computing position and/or speed signals from satellite signals, a second circuit part, which is made as a real-time clock to provide a time signal, at least two voltage sources, which are provided to supply at least one circuit part, and switching means, which are provided for switching the supply of at least one circuit part between the first voltage source and the second voltage source. According to an embodiment, the switching means have at least one voltage monitor with a bandgap voltage reference circuit to determine a switching voltage. The circuit arrangement can be used for GPS-supported navigation systems.
