GPS Module Requires Little Housing Space
Measuring a paltry 7 by 7 by 1.4 mm, the ORG4472 from Round Solutions may be the smallest GPS module known to market (see the figure). The automotive/industrial-compliant module employs the company’s SiRF IV chipset.
According to Olaf Schaefer, technical director at Round Solutions, “This new SiRFstar IV chipset of the module provides higher sensitivity and consumes less power than previous GPS systems. This extends battery life especially for small handheld devices because now passive GPS antennas can be used without losing performance.”
The ORG4472 is a surface-mount module. There is no cost for RF connectors or cables, and no manual work is necessary in production. Its integrated interface for accelerometers, gyrometers, or other sensors makes dead reckoning a fairly easy task.
A datasheet for the ORG4472 is available at www.roundsolutions.com/techdocs/ds/ORG447X_Series_Datasheet.pdf.
