1. A self-localizing apparatus for determining a vehicle's position, the self-localizing apparatus composing:
a first subsystem, comprising:
a first antenna operable to receive a first radio frequency signal;
first analog reception electronics configured to amplify the first radio frequency signal;
first digital reception electronics configured to timestamp the amplified first radio frequency signal with reference to a clock signal; and
a first localization unit configured to compute a first estimate of the self-localizing apparatus' position in a coordinate system based on the timestamp of the amplified first radio frequency signal; and
a second subsystem operably coupled to the first subsystem, comprising:
a second antenna operable to receive a second radio frequency signal;
second analog reception electronics configured to amplify the second radio frequency signal;
second digital reception electronics configured to timestamp the amplified second radio frequency signal with reference to a clock signal; and
a second localization unit configured to compute a second estimate of the self-localizing apparatus' position in a coordinate system based on the timestamp of the amplified second radio frequency signal; and
wherein each of the first subsystem and the second subsystem is configured to be selectively used to control the vehicle without relying on the other subsystem.
