BoB Product Requirements Specification 26 February 1999 1. System Description 1.1 User Features The following table identifies the operational features for BoB. ITEM SPECIFICATION NOTES Beacon Receiver Antenna Built-in Omni-directional Beacon Almanac BoB must store the last recorded beacon almanac. This is to be updated whenever a more recent almanac is received Beacon Channel tracking Tracks 2 channels simultaneously Wireless Link Transmitter only, license free frequency band.
BoB Product Requirements Specification 26 February 1999 1.2 System Operation 1.2.1 Modes of Operation BoB will track frequencies using one of two modes: Best and Fixed. The list of frequencies that can be tracked, plus the startup mode, can be controlled using PC-BoB software. Normally users will either have a very short include list (e.g. one to five stations) or will have a very long include list (excluding only one or two dominant stations).
BoB Product Requirements Specification 26 February 1999 1.2.1.2 Fixed Fixed mode means that BoB will track one frequency consistently until the user intervenes.
BoB Product Requirements Specification 26 February 1999 1.3 User Interface the user interface on BoB • Power on and off • Switch between best and fixed modes • Total power off • Reset unit to defaults • To scan through either a user list of frequencies, or through the range of beacon transmissions available at the time. • The user feedback showing the following • Whether the unit is on or off. • Battery charge status • Beacon tracking status 1.3.1 LED interface It is a dual colour, green and orange.
BoB Product Requirements Specification 26 February 1999 The following table contains the same information but the axes are colour states.
BoB Product Requirements Specification 26 February 1999 1.3.1.1 LED Events In addition to the above LED states, the LEDs will flash to indicate events. The events and LED codes are outlined in the following table. Event LED Code Wireless enabled (see section 1.3.2.2) Beacon LED flashes green at 4Hz for 1 second Wireless disabled (see section 1.3.2.2) Beacon LED flashes orange at 4Hz for 1 second Reset to Factory Defaults initiated (see section 1.3.4.1) Both LEDs flash green at 2Hz for 2 seconds 1.
BoB Product Requirements Specification 26 February 1999 1.3.2.2 Beacon Button Functionality Short Press (<0.25 second) • The short press operation on the beacon button has a number of similar functions. If in Best mode, the short press operation will force the beacon receiver into Fixed mode and will lock the frequency to the frequency currently being tracked. Performing further short press operations will move to the next frequency in the list of enabled frequencies.
BoB Product Requirements Specification 26 February 1999 1.3.4.1 Dual Button Operation Dual button press (5 seconds) • The Dual button press operation resets the configuration of BoB. Performing this operation is a cold boot of the BoB receiver. It clears any configuration sent from PC-BoB, as well as the current almanac. 1.3.5 Best Mode station tracking This section has been incorporated into section 3.2.1.1. 1.3.6 Firmware upgrade Winflash be used as the mechanism to put the firmware onto BoB.
BoB Product Requirements Specification 26 February 1999 1.4 BoB Sub Systems 1.4.1.1 Beacon channels There are to be two channels (Primary and Secondary). Best Mode Fixed Mode Primary Channel Pass RTCM through to Datalogger Pass RTCM through to Datalogger Secondary Channel Searches for the second Best frequency Searches for next frequency on the filter list (if 42 or more frequencies available from user’s list) or track the next frequency (if less than 42 frequencies available) 1.4.1.
BoB Product Requirements Specification 26 February 1999 1.4.1.5 Beacon Antenna A internal antenna has been selected. It is not a requirement to connect to an external antenna. 1.4.2 Mechanical The following information is detailed herein and does not necessarily appear in the mechanical specification. The specification will detail the how and why of obtaining the following product level specifications. Mounting • BoB will be supplied with a pouch that will allow BoB to be easily removed from the pouch.
BoB Product Requirements Specification 26 February 1999 1.4.3 Configuration Manager Software The configuration of BoB will be done through a Windows based configuration program called PC-BoB. Basic configuration of BoB can also be achieved on the unit itself. A complete description of the configuration manager software can be found in “PC-BoB Specification”. Configuration parameters and how they are communicated to BoB are described in the BoB Software Specification. 1.4.
