Flextrack Lommy

Lommy by Flextrack ApS

The Lommy™ offers an unseen level of GPS tracking inside most buildings and at places where traditional GPS tracking devices fail to deliver stable performance.

The Company

Flextrack, located in Denmark and a subsidiary of the Jax Corporation, develops and manufactures advanced telemetric equipment based on GPS, GSM, and GPRS. Flextrack devices are small, easily configurable, and excel in ease-of-use by the end user. Flextrack's vision is to implement technology for the sake of the user, not for the sake of the technology.

The Product

Following that vision, the Lommy™ personal tracker needed to be small, easily configurable, have long battery life, and provide excellent tracking performance in all conditions. The Lommy offers tracking through GPRS and SMS messaging to a central server, and has simple one-button dialing to emergency services with GSM voice. For GPS, Flextrack turned to two leaders in providing high-sensitivity GPS receiver and antenna technology for difficult user environments: Orcam and Sarantel.

Orcam Systems, a leader in GPS modules based on the SiRFstar IIe/LP low-power, 12-channel GPS chipset, supplied Flextrack with the Orcam 21 Series module, designed to draw only 60mA in full power mode and as little as 20mA on TricklePower™. The Orcam module tracks satellite signals down to -152dBm, allowing Lommy to get a position fix in highly attenuated environments.

Sarantel's antenna provided the other side of the performance equation for Flextrack. Designed to retain efficiency when near other objects, the GeoHelix-SMP passive GPS antenna ensures that the maximum signal level is passed to the GPS receiver in conditions that would drown out other antennas.

The Proof

To demonstrate the robustness of its innovative personal tracking solution, Flextrack organized "the Tour de Lommy," a 150 mile trip via the Danish postal service from Hedensted to Aalborg.

The Lommy was wrapped in an anti-static shielded plastic bag and placed in a conventional cardboard container with additional packing material. The package was then placed in a car and delivered to the local post office. After a couple of hours, the package was loaded in a postal truck with a closed aluminum cargo space, together with all the other mail, driven to the local sorting facility, and finally delivered the next morning. During the entire 60 mile trip the Lommy transmitted geo-coordinates every two minutes with position, direction, and speed. At no time did the Lommy get lost! Further, the Tour was repeated several times, including dropping the Lommy into a standard metal post box where it continued to track its position.

Their Comment

Carsten Groen, Flextrack's Development Manager, says that "Orcam and Sarantel have delivered a tracking performance that enables some amazing applications. Consumers need technology to just work. Orcam?s high sensitivity with SiRF's low-power chipset and Sarantel's imperviousness to loading from materials - and people - around the antenna ensures that the user can depend on the Lommy when they need it. Operating the Lommy will require no special technical knowledge on the part of the user. Taken together, this will ensure a broad adoption for the Lommy."
