ELECTRONIC LOGBOOK
First Claim
1. Electronic logbook in an appliance (1) which can be used removably in a vehicle holder (2), containing a satellite position-finding module (22) for reception of satellite data and for outputting position data, derived from the satellite data, and time data, an association device for association of mutually associated position and time data, and a non-volatile memory device for the associated position and time data, wherein the electronic stages in the housing are supplied with electricity via a connection from an on-board power supply system in the vehicle, characterized in that, when the appliance is disconnected from the on-board power supply system, a residual power supply is provided which keeps the appliance (1) operable for a short time and controls immediate storage of the most recently determined position and time data with a marking,in that, when the appliance (1) is inserted into the vehicle holder (2), a clock with a fictitious starting time is controlled,in that, when satellite data is received again, position data and current time data are determined, and in that the time which has passed on the clock before determination of the current time data is used to determine the time when the appliance (1) was inserted into the vehicle holder (2).

Abstract
An electronic logbook in an appliance (1) which can be used removably in a vehicle holder (2), containing a satellite position-finding module (22) for reception of satellite data and for outputting position data, derived from the satellite data, and time data, an association device for association of mutually associated position and time data, and a non-volatile memory device for the associated position and time data, wherein the electronic stages in the housing are supplied with electricity via a connection from an on-board power supply system in the vehicle, can be protected against manipulation by removal of the appliance (1) from the vehicle holder (2) in that, when the appliance is disconnected from the on-board power supply system, a residual power supply is provided which keeps the appliance (1) operable for a short time and controls immediate storage of the most recently determined position and time data with a marking, in that, when the appliance (1) is inserted into the vehicle holder (2), a clock with a fictitious starting time is controlled,
in that, when satellite data is received again, position data and current time data are determined, and in that the time which has passed on the clock before determination of the current time data is used to determine the time when the appliance (1) was inserted into the vehicle holder (2).
