SYSTEM REQUIREMENTS Functionality defined within this NorthStar document is an enhancement to the current system,adding functionality with a new interface to allow CAD/GPS functions, including AVL.Only a portion of the functionality will be site configurable.This interface is available only for sites operating with the NorthStar CAD/INMOTION Mobile Gateway interface. DEFINITIONS In this document,Logistic Systems,Inc. is referred to as LogiSYS;the vendor of the NorthStar CAD system. The user or you refer to the operator or dispatcher using NorthStar CAD. Words appearing within brackets,< >,denote a variable.An appropriate value replaces the<>and the word inside the brackets.For instance,<Hydrant ID> indicates that Hy d rant ID will be replaced by an actual Hydrant ID;for example, F750MAIN. 1-1 NORTHSTAR FUNCTIONAL SPECIFICATION w0#120520 INMOTION MOBILE GATEWAY INTERFACE 2 CLIENT REQUIREMENTS (SCOPE) PURPOSE/GOAL This enhancement will fulfill the LogiSYS contract requirements with the County of Orange to establish communication between the NorthStar CAD system and GPS-enabled units equipped with INMOTION Mobile Gateway. This new functionality will: 1.Provide the capability for the NorthStar CAD system to receive GPS data directly from the INMOTION Mobile Gateway and display icons representing the Mobile Gateway equipped units' positions on the NorthStar CADMap. 2-1 NORTHSTAR FUNCTIONAL SPECIFICATION WO#120520 CAD/INMOTION MOBILE GATEWAY INTERFACE 3 API DESIGN SPECIFICATIONS INTRODUCTION This NorthStar interface provides a mechanism for the LogiSYS NorthStar CAD system to communicate with GPS-enabled units by way of the INMOTION Mobile Gateway.This document describes program specifications for GPS- enabled units to perform CAD-related functions in coordination with the NorthStar CAD system. SYSTEM REQUIREMENTS This LogiSYS interface enables NorthStar to receive information for the functions described in this document from the INMOTION Mobile Gateway using the User Datagram network protocol. OVERVIEW Communication of GPS data between GPS-enabled units and the NorthStar CAD system is dependent on the functionality contained within the CAD/INMOTION Mobile Gateway interface.The NorthStar CAD system provides for a broad array of functionality involving GPS-enabled units. This document describes and defines some of those functions. 3-1 NORTHSTAR FUNCTIONAL SPECIFICATION WO#120520 CAD/INMOTION MOBILE GATEWAY INTERFACE Section I: Automatic Vehicle Locator (AVL) The Automatic Vehicle Locator,or AVL,is a feature that allows NorthStar to plot the location of a vehicle that is equipped with a Global Positioning System (GPS)on the CAD map. The MMOTION Mobile Gateway sends NorthStar the unit's position in latitude and longitude and vehicle ID at a given time.NorthStar converts this data, received directly from the MMOTION Mobile Gateway into the projected coordinates used in the NorthStar system.NorthStar then plots the unit as an icon on the CAD map. How often NorthStar receives updates of the unit's position can be configured on the Mobile Gateway.NorthStar then updates the position of the unit on the map if the unit moves more than 300 feet(a configurable value). GPS Data Reception from the INMOTION Mobile Gateway The NorthStar interface listens for UDP datagrams on a configurable port. After the datagram is received,the interface interprets the TAIP sentence sent by the MMOTION Mobile Gateway. Since the protocol does not have the reliability of TCP/IP, some packets may be lost but this will not affect the operation of the system. Note: Configuration of the Mobile Gateway, including the assignment of the TAIP PV message type, the Vehicle ID, and the IP address and port number for Remote Forwarding to the Northstar interface is the responsibility of the client. Each Mobile Gateway must be configured wih an unique Vehicle ID corresponding to a valid Northstar unit. The client must also provide suitable interface devices such as cellular air cards or Wi-Fi cards and configure the Mobile Gateway's WAN connection to allow the UDP packets to be transmitted to the server hosting the CAD interface. 3-2 4 NORTHSTAR FUNCTIONAL SPECIFICATION WO#120520 CAD/INMOTION MOBILE GATEWAY INTERFACE The TAIP sentence is in this format: >RPV 15714+3739438-1220384601512612;ID=1234;*7F< The NorthStar interface parses the sentence for the following fields and content: > Start of Message Delimiter R Response Qualifier PV PV Message Identifier 15714 GPS Time of Day +3739438 Latitude -12203846 Longitude 015 Speed 126 Heading 1 Source of Data 2 Age of Data ;ID=1234 Vehicle ID ;*717 Checksum < End of Message Delimiter Note: Within the NorthStar CAD system for the County of Orange,each INMOTION Mobile Gateway device must be mapped to a valid CAD subunit. In order for a unit's location, `MEDIC 1' or`MEDIC 5' for example,to be displayed on the CADMap,the subunit must be attached to the unit after the unit is logged onto the system by a NorthStar CAD system dispatcher. If a unit is transferred to another subunit,the current subunit must be detached and the new one attached.Failure to follow the abovedefined process in a timely manner can result in units being incorrectly tracked by AVL and displayed in the wrong location on the map. When a unit goes to an off-duty status,any attached subunit is automatically detached. If a position update is received from a subunit representing an INMOTION device and the subunit is not attached to a CAD unit,a warning message will be sent to all CADMsg applications. 3-3
