Product Description
The Jupiter SE878K3-A GNSS antenna module is a com-
plete multi-constellation GNSS receiver featuring a high
sensitivity 17 x 17 mm patch antenna, SAW filter, addi-
tional LNA, flash memory, GNSS core, RTC and TCXO. The
SE878K3-A uses Telit’s “cavity like” PCB package with
an optimized RF path supporting standard SMT mounting
without constraining the host PCB, minimizing the antenna
detuning.
The SE878K3-A support GPS, QZSS and GLONASS, Beidou
and it is Galileo ready. The SE878K3-A is capable to track
GPS + GLONASS (or Beidou) and Galileo constellations
simultaneously, providing the positioning data though
standard UART and I2C.
The Jupiter SE878K3-A supports either autonomous than
server based A-GPS. Its onboard A-GPS software engine
is able to locally predict ephemeris up to three days in
advance and store this data in the memory.
Easing the development process for designers with little
or no RF experience, the SE878K3-A is compliant with
regulatory and industry standards specifications. Addition-
ally, it supports the usage of an external antenna through
an embedded RF switch. This feature is particularly useful
in applications such as personal trackers and alarms in
which the main antenna is the external one and the internal
antenna is used as backup when the external is broken or
compromised.
The SE878K3-A is designed to Telematics, Tracking & Trace
and Alarm applications.

Family Concept
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 counter-
part GLONASS. Moreover, our portfolio is fully aligned with
the upcoming service launch of Europe’s Galileo constella-
tion. 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.
Your application development effort can also benefit sig-
nificantly from the seamless integration between Telit’s 2G
cellular and positioning modules. This bundling of cellular
and positioning modules significantly reduces develop-
ment complexity without adding costs. Multi- constellation
positioning products applied together with our eCall/ERA-
GLONASS compliant cellular modules bring you ready-
to-use 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.
