A disclaimer is in order: I am not an

expert on the many mass market GPS

navigation devices in the hands of millions

today, so please do not expect a compara-

tive analysis. As far as I know, AvMap is

the only maker of GPS navigation systems

with hardware and software specifically

designed to support APRS, the Amateur

Packet/Position Reporting System devel-

oped by Bob Bruninga, WB4APR — end

of comparative analysis.

The Geosat6 (G6) is the latest in a

series of GPS navigation systems by the

Italian maker AvMap that are designed to

be integrated into mobile APRS installa-

tions. The G6, like its predecessors the G4

and G5, has a serial port to interface with

Kenwood APRS capable radios, the Byon-

ics TinyTrak4 (TT4, see the accompanying

sidebar), or pretty much any 2-meter radio

and terminal node controller (TNC) with

APRS capability.

The G6 includes several

significant differences compared to the G4

and G5. In addition to smaller overall size;

it has much higher display resolution and

an awesome magnetic mounting system.

My first impression when I opened the

box was “Oh no! — They made the G6 too

small.” I really liked the relatively large

display of the G5. After I got the G6 work-

ing, I realized that its display is unbelievably

sharp, and it’s controlled by a touch screen

so there are no hard buttons taking up space

on its face. These two factors support the

reduced size with virtually no reduction

in readability. The fonts used scale up and

down or disappear depending upon map

zoom level, and they are quite readable.

APRS positions have crisp icons and a block

font that does not wash out or get lost in the

background. Normal fonts are black with

white background, so they also stand out

on the map. Clarity is supreme on the G6.

Overview

The G6 measures 3

(height, width, depth) compared to 4

resolution of 480 × 272 pixels, and supports

65,536 colors. By the way, the display is

actually 4.8 inches diagonally in a wide-

screen format — not really much smaller

than the G5, yet in a smaller, handier overall

package.

The connectors and hard controls are

mostly on the right flange and include I/O

SERIAL port, USB port, AUDIO OUTPUT,

POWER jack and POWER switch. There are

also internal SPEAKER ports on both sides of

the frame. The bottom flange has the main

power ON/OFF switch, RESET and SD CARD

slot. The rear panel has a daylight sensor and

proprietary keyed four point POWER con-

nector that mates with the magnetic mount

(more later). The CPU runs at 520 MHz,

and is supported with 64 MB of RAM. The

operating system is Windows CE. It weighs

in at 9.7 ounces.

What Comes in the Box

The G6 comes with everything you need

to power the unit and charge the internal

Li-ion battery, and interface with Kenwood

APRS capable radios and computer. There

is an ac charger in addition to the dc ciga-

rette lighter cord. The ac charger plugs into

the POWER port on the side of the G6. The

dc cord plugs into the included magnetic

mount, which contains a voltage regulator

circuit that converts a 12 V source to 5 V. An

included CD-ROM contains the instruction

manual and desktop software called Geosat

Suite. A 4 GB SD card containing Navteq

mapping for North America and Mexico

comes with the G6. The G4 and G5 use

TeleAtlas mapping. An on-the-glass suction

cup mount is also included.

More on the Magnetic Mount

The magnetic mount has four slots on its

rear that mate with the on-the-glass mount.

On its front, there are four powerful magnets

around electrical contacts that mate with the

keyed gold contacts on the rear of the G6

(see Figure 5). There are actually two sets

of contacts in a recessed socket that allow

the G6 to be viewed in either portrait or

landscape mode by simply rotating the G6

in the mount accordingly (Figure 6). The

magnets are strong enough to hold the G6

tight, even on the bumpiest roads, but it is

easy to pull the G6 off the mount and take

it with you when you leave your vehicle.

Power

I mentioned that there is a main power

switch on the bottom flange in addition to

a power button on the side. When the main

switch is off, the G6 is completely off. When

the main power switch is on and the G6 is

connected to an external power source, the

internal battery will charge. In this mode the

G6 senses the presence or absence of exter-

nal power and will go into standby mode

— display off, but GPS receiver engine and

position cache memory remain on — until

external power is sensed.

This conserves power while allowing

for faster position acquisition by using the

internal battery for power. This mode is

great when you are in and out of your vehicle

Bottom Line

The AvMap Geosat6 APRS

navigator builds on the success of

the G4 and G5. The new version

is smaller and more capable than

previous models, yet it is still easy to

hook up and use.
