3.7 Data Capacity
B Tip
Introduction to the TSC1 Datalogger 3
The TSC1 datalogger is supplied with 2 MB of internal memory for
data storage, which in most cases provides enough capacity for your
data logging requirements. Table 3.2 provides estimates of the data
logging capacities of the TSC1 datalogger under various data
collection scenarios. Although the TSC1 can hold a large volume of
data, Trimble recommends that you transfer data files to your office
PC daily.
Table 3.2 Data capacities for rover and base files
File type Logging interval Carrier logging Logging time
Rover 1 second On 2 - 2.5 hours
1 second Off 6 hours
5 seconds On 10 hours
5 seconds Off 30 hours
Base 5 seconds 14 hours
15 seconds 35 hours
Note – For the highest accuracy of differentially corrected positions,
Trimble recommends that the rover position interval be set to a
multiple of the base station interval.
– If you must log data for longer periods, you can increase the GPS
logging intervals.
If you require more memory for data storage than is available in the
TSC1 datalogger’s internal memory, use a PC card.
