Product Description
Family Concept
The JF2 offers developers and integrators the smallest,
completely integrated GNSS solution for positioning applications based on a 1.8V supply. It is fully interoperable with
Telit cellular modules for a ready-to-use solution bundle
with no additional integration effort or cost. The JF2 can be
managed by an external microcontroller or by any of the
Telit cellular modules.
Our positioning product portfolio is the result of over twenty
years of experience in GNSS applications. Telit has developed
a range of products compatible with the well-known GPS
constellation as well as its Russian counterpart GLONASS.
Moreover, our portfolio is fully aligned with the upcoming
service launch of Europe’s Galileo constellation. Valuable
features such as Dead Reckoning, Precision Timing, as well
as speed and reliability assured by multi-constellation coverage, provide additional benefits for your application.
Key features

• GNSS supported: GPS L1
• 11x11x2.6mm QFN package
• Flash, EEPROM or ROM based versions
• Assisted GPS
• High RF sensitivity with jamming detection and removal
• Supply voltage range: 1.79-1.9 VDC
• Advanced power modes
• Ports: 1PPS, UART, I2C and SPI
Key Benefits
•Supports AGPS using Extended Ephemeris injection as
well as Extended Ephemeris on-board generation
for fastest TTFF
•Easy integration in cellular/GNSS bundle solutions
with Telit cellular modules
•GPS solution with embedded Flash: high performance,
always up-to-date and lowest BOM cost and footprint
Combine your
GNSS module with
Short Range
Your application development effort can also benefit significantly from the seamless integration between Telit’s 2G
cellular and positioning modules. This bundling of cellular
and positioning modules significantly reduces development complexity without adding costs. Multi-constellation
positioning products applied together with our eCall/ERAGLONASS compliant cellular modules bring you ready-touse emergency automotive tracking solutions for the
European and Russian markets.
Typical applications include fleet management systems,
European GPS-assisted road tolling systems, cellular base
stations, in-car navigation systems, automotive telematics
systems, and GPS-based personal sports training monitors.
