Positioning with data link is not the same as referenced positioning (a method that allows measurements from more than one receiver to be combined and processed together in order to enhance accuracy), This external information includes measurements from other receivers, but it also includes other information which can be used to improve not only accuracy, but also other parameters in the specification, such as TTFF and sensitivity. It is very important for many applications to be able to provide instant positioning, i.e. to avoid the necessity of tracking a satellite signal and reading a navigation message. It takes up to 36 s to read a complete navigation message for a GPS L1 signal to ensure the decoding necessary for positioning data. If navigation message data are available through some other data link, it is still necessary to decode a time mark from the navigation message, which may require up to 6 s. BGPS (and AGPS before that) are very important for many applications because th

Indoor Housings Indoor housings must protect the  Home Security Cameras  and lens from pollutants such as dust and other particulate matter, a corrosive atmosphere, and tampering or vandalism. Indoor housings are constructed of painted or anodized aluminum, painted steel, stainless steel, and several types of plastic. The material for plastic housings must be flameproof or flame-retardant, as designated by local codes and UL recommendations. The housings must have sufficient strength to protect the lens and camera, and be sturdily mounted onto a fixed wall or ceiling mount, or recessed in a wall or ceiling. The lens should view through a clear window made of safety glass or plastic. Recommended plastic window material is either high impact acrylic or polycarbonate with a mar-resistant finish. The electrical input/output access locations should be designed and positioned for easy maintenance. For easy access and servicing of internal parts, the top half of the housing should be hin

Personal Tracking Device  is allowing elderly people and those with limited functionality to live independently longer, with caretakers doing their work remotely. General Electric, for example, has a product in which ubiquitous sensors can accurately and unobtrusively determine an independent elderly person’s activity. Currently, simple tracking systems are more common, such as a GPS-programmed “geofence” that sends an alert to a caretaker if the person has left a predefined area. The device is targeted to people who suffer from Alzheimer’s disease, although it can be used with children and teenagers as well. Lawmakers should be more aware of the possibility of caretakers abusing devices such as the i-TAG and the more sophisticated sensor systems. If an abused person leaves his or her home to escape, the caretaker would be notified instantly. And if gadgets or software monitor call logs as well, an abused person might have even more limited recourse. The abusive caretaker situatio

The joystick is moved forward or backward, left or right corresponding to the vertical (tilt) and horizontal (pan) movements of the camera/lens unit. Likewise, the thumb trackball is moved using the thumb to initiate pan and tilt. For the disk, touch-pad, and four-button design, left and right initiate panning, and top and bottom initiate tilt. The security officer watches the video monitor and can point the  Wireless Camera  to view any area within the pan/tilt rotation range. The platform and camera move in accordance with the control signal sent by the control unit. Pan/tilt platforms are available in a wide range of sizes from lightweight, pan-only units (scanners) for indoor applications to heavy-duty, environmentally protected pan/tilts for outdoor applications. Rugged outdoor units are environmentally enclosed and intended to withstand severe conditions of temperature, precipitation, dust, humidity, and high winds. In the late 1990s the requirement for faster, more compact,
