1.0 PURPOSE
The SHOUT ns is a pocket-sized, low-cost, low-power, Iridium satellite network tracking
device. It is designed to relay, via the Iridium satellite network, GPS location data and other
critical data such as emergency messages, geofence data, and callouts from the device and
text messages from the NAL SHOUT smart phone app. It has a rugged plastic housing with
embedded Iridium, GPS, and Bluetooth antennas. This device can easily be carried by a person
or attached to high value, un-tethered or non-powered assets.
The SHOUT ns comprises an Iridium 9603 transceiver module, a built-in 72-channel u-
blox GPS receiver, and low power micro-controllers. The SHOUT ns can send short-burst data
(SBD) messages over the Iridium satellite network. The SHOUT ns can transmit messages in
NAL Research's defined report formats compatible with models 9602-LP, 9602-AB, the A3LA
series modems, and SHOUT series tracking devices. The SHOUT ns can also transmit in PECOS
Message Structure (PMS). The PMS complies with the Blue Force Tracking Data Format
Specification as defined in the document PECOS Message Definition Specification, 200907-
001 Version 1.7 [3]. When requested by an authorized user, NAL Research can enable the
SHOUT ns to utilize the DoD DISA EMSS (Enhanced Mobile Satellite Services) Gateway when
sending over the Iridium satellite network.
IMPORTANT: EMSS-enabled SHOUT ns must first be provisioned (signed up
for airtime) with EMSS SBD Service before testing or field use. Accessing the
DoD EMSS Gateway is not authorized until the SHOUT ns is provisioned.
Unauthorized attempts to access the DoD EMSS Gateway will result in
immediate disabling of the offending device, which must then be returned to
NAL Research for repair. See
regarding EMSS service provisioning.
The SHOUT ns is designed with ultra-low power consumption electronics. It is capable of
delivering uninterrupted service for up to 20 days at one report per hour. Power consumption
can be further reduced by using the device's built-in motion sensor and/or geofencing features
to reduce reporting frequency when a platform is not in motion or is outside an area of
interest. In addition to normal tracking, the SHOUT ns also has a real-time clock allowing
power-up delay as well as scheduled daily Call Outs.
Externally, the SHOUT ns has two buttons and six LEDs to provide the user control and
status of the device. The six LEDs provide the status of power state, battery charging status,
GPS fix, Bluetooth connection status, report transmission status, and Iridium connection
