V3d Product Specification, Version 2.06
1.0 Scope
1.1 Purpose and Overview
This document provides a complete product specification for the V3d and in part its predecessor
the V3c. All application-level environmental, mechanical, electrical and functional requirements
are specified, sufficient to enable development and subsequent design verification of the V3d
product. A separate document, the SPC GlobalTrak Over-The-Air Protocol Specification,
defines the air interface for satellite and cellular communications with the V3d. Note that many
component-level requirements are not listed here, for example GSM or ORBCOMM transmit
spectral masks, since such components are previously certified devices and integrated without
significant modification into the overall V3d product.
The V3c prototype version is best considered an entry level product designed to meet the basic
requirements of the intermodal sea container market. As such, it is limited in its functionality
and performance and will not meet all the requirements detailed in this document and the
accompanying OTA Protocol Specification.
1.2 Audience
This document is intended for V3d design, development and quality assurance personnel
employed by SPC or MobiApps.
1.3 Revision Control
This document will be released under version numbers less than 1.0, until at such time it is
considered to represent the customer needs at a level sufficient for the generation of detailed
design specifications. Each release version will be listed in the Revision History sheet included
in the third page of the document.
1.4 Conventions
Normal descriptive text is shown in a normal font.
Narrative or explanatory text is shown with emphasis.
Items requiring special attention are in bold.
1.5 Priorities
The requirements listed in Sections 3, 4 and 5 can have any of the priorities defined below. Any
requirement not specifically noted is a “high priority”.
High Priority [HP] – must be included in the production build but not necessarily the prototype
build. In some cases the requirement is most likely met in the prototype build, but will not be
formally verified, for example mechanical requirements related to shock and vibration.
Prototype Priority [PP] – must be included in the prototype build.
