NSL have developed
primo,
a Software Defined Radio (SDR) GNSS
receiver.
primo tracks and utilises
signals from the full complement of GNSS systems,
including GPS, Galileo,
GLONASS, Compass, EGNOS, GAGAN, MSAS
and WAAS. |
 |
primo is a
fully functional GNSS
receiver that is configured for optimal
signal acquisition, tracking and positioning dependent on the target application. Applications of
primo
include
- Ground Reference Stations
- Transport-based, High Fidelity Applications
- Professional Navigation, Monitoring and Surveying
- Signal Quality and Multipath Monitoring
- Interference and Jamming Detection
- GNSS Validation
Please see the datasheet for product information. Ordering information and pricing for the CPLD Front End can be found at the following page.

WHAT IS A
GNSS SDR?
Within a SDR
GNSS receiver, the
analogue signal is
received by the antenna and is fed
into a RF (radio
frequency) hardware
front-end which
converts the signal
into digital form.
The digital signal
representation is
passed to a
computing device
which, through
software, undertakes
the signal
acquisition, timing
recovery, signal
tracking, message
decoding and,
ultimately, the
calculation of
position, velocity
and time.
Software defined
radio technology has
the potential to
revolutionise
satellite navigation
services, as it
enables satellite
navigation services
to be readily
upgraded with a
simple firmware
upload, moving the
industry and
associated market
from being product
driven
to being service
oriented and focused
on the provision of
applications.
