|
Trimble’s Lassen® iQ module is
one smart buy. It adds powerful,
12-channel GPS unctionality
to your mobile product in a
postage-stamp-sized footprint
with ultra-low power consumption
and extreme reliability?all
at a very economical price.
Designed for portable handheld,
battery-powered applications
such as cell phones, pagers,
PDAs, digital cameras, and many
others, the module is also ideal
for standard GPS applications
such as tracking.
The 12-channel Lassen iQ
module is fully compatible with
Trimble’s popular Lassen SQ
module. Using Trimble’s breakthrough,
patented FirstGPS®
architecture, the module delivers
complete position, velocity and
time (PVT) solutions for use in
the host application.

|
Acquisition |
|
(Autonomous Operation in Standard Sensitivity Mode)
| Reacquisition: |
|
<2 sec. (90%) |
| Hot Start: |
|
<10 sec (50%), <13 sec (90%) |
| Warm Start: |
|
<38 sec (50%), <42 sec (90%) |
| Cold Start: |
|
<50 sec (50%), <84 sec (90%) |
Cold start requires no initialization. Warm start implies last
position, time and almanac are saved by backup power. Hot
start implies ephemeris also saved. |
