1 INTRODUCTION
The GNS1001 module utilizes the new generation MediaTek MT3339 GPS chip.The navigation
performance and accuracy is further improved by using correction data from SBAS (WAAS, EGNOS,
GAGAN, MSAS),QZSS or connectivity to DGPS(RTCM format).
First Fixes after just a few seconds are achieved with the help of A-GPS using EPOTM ( Extended
Prediction Orbit) and the EASYTM “self generated orbit prediction” algorithm. EASYTM (Embedded
Assist System) does not require any resources or assist data from the host.
The excellent low power design makes it easy to implement this module in power sensitive, battery
supplied applications. The new AlwaysLocateTM power management feature will improve this
behaviour additionally. It adaptively adjusts power consumption depending on the environment and
motion conditions, in order to achive a balance between fix rate, power consumption and position
accuracy.
Very low power requirements (typ 49mW@ 3.3V) and internal voltage regulator makes it easy to
run the module with various power supplies and allows direct connection to LiIon batteries.
GNS1001 offers the industry’s highest level of navigation sensitivity up to -165dBm. It has superior
dynamic performance at high velocity and provides effective protection against interference signals
using MTAICTM ( Multi-tone active interference canceller). Up to 12 independent channel
interference continious wave jammers <-80dBm can be eliminated or reduced.
The embedded logger function LOCUS with a 16-hrs on chip memory makes this GPS module a
complete track logger for many applications. With AlwaysLocateTM data logging can be achieved up
to 32-hrs under standard conditions.
In professional timing applications the outstanding high accuracy PPS (pulse per second) hardware
pin is used for synchronization to GPS second. Typical accuracy is 10ns.

3.3 Power management features
Power management schemes implemented for any GPS system requires an optimally tuned
performance for both accuracy of the position fixes and the average power consumed for best user
experience. GNS1001 architecture achieves both these aspects by providing flexibility and design
choices for the system integration based on wide range of use cases and by leveraging on the
proven silicon methodologies. Also GNS1001 provides position, velocity and time measurements
without any host loading. This, coupled with the optional built-in power management options,
reduces the overall system power budget.
Power management features:
In Standby mode RF frontend and internal MPU are switched to deep sleep state. Power
consumption is reduced to 0.63 mW (190µA).This state can be entered by sending the NMEA
command: $PMTK161,0*28<CR><LF>.
Leaving standby mode and resuming to normal operation will be managed by sending any
byte to the module.
Backup mode can be entered by sending NMEA command: $PMTK225,4*2F<CR><LF>.
The GPS core will shut down autonomously to backup state, Vcc supply can now be switched
off by an external power supply switch.
Periodic mode describes a power mode, which will autonomously power on/off the module
in programmable time slots with reduced fix rate. Periodic mode is useful during stationary
operation or if position fixes are just needed from time to time. Since power consumption in
GPS off times is nearly zero, the power consumption in periodic mode can be estimated by
Ptracking * (ton/(ton+toff)).
Periodic mode is controlled with NMEA command $PTMK225. See document
NMEAcommandInterface manual for programming details.
