Anything in the path between you and the base station can block the signal. Especially trees and buildings. If you have a clear, optical, line of sight it will almost certainly work.

Yes, both will diminish the signal. For that reason you will need a clear line-of-sight to one of our access points. Yes and no. Large amounts of rain or snow may diminish the signal, but wet weather also evens the air temperature. This reduces problems with interference issues such as fade drift, thereby increasing your speeds. At most you may see a 10% reduction in speed during a heavy rain or snow storm.

GPS signals available to civilian GPS receivers can be used to compute position to within 10 meters (33 feet) most of the time. However, the precision of the GPS signals is sometimes intentionally diluted in certain sensitive areas based on national security needs. GPS signals are available all over the world.

In most cases you will need a clear line of sight to the tower. Microwaves at frequencies of 2.4 and 5.8 GHz do not travel well through foliage and solid objects. We do have 900 MHz NLOS (non line of sight) equpment in selected areas with a lot of trees.

Yes, the signal can pass through walls and buildings, depending on what the wall is made of or what is in the wall. Walls with sheet metal covering may reflect the signals, so the radio waves will not penetrate it. Also walls with lots of wiring and poor wiring insulation may cause interference and degradation of signal, and hence, poor performance.

A GPS receiver only works outside because it needs a line-of-site path to the GPS satellites. Any object can block the line-of-site - trees, buildings, roofs, bags, bodies, even clothes. For cyclists, the best place to place your GPS is mounted on your handlebar. Or we have found that placed in the back pocket on your jersey, facing up to the sky produces an acceptable signal. Runners should strap their GPS on their arms or wrists.

Signal multipath : The GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver. Orbital errors : Also known as ephemeris errors, these are inaccuracies of the satellite's reported location. Poor satellite visibility : The more satellites a GPS receiver can "see", the better the accuracy. GPS units typically will not work indoors, underwater, or underground.

There are known issues with interference, including (but not limited to) amateur radios, existing microwave towers or antennas, and other 2.4 or 5.8 Ghz wireless devices. If you have a 2.4 Ghz cordless phone, you will need to locate it at least 10 feet away from your computer, antenna cable, and/or antenna.

Why don’t genealogists use the simple terms “primary source” and “secondary source?”

Yes, the Road Angel is NMEA compatible and communicates at 9600-baud rate. This means that it can be used with some Route Mapping software for Satellite Navigation. We recommend using InfoMap™ from Directions Limited. www.directions.ltd.uk. NB: The Road Angel is NOT compatible with Microsoft Autoroute™. Please note that we can only provide technical support for the Road Angel.

Sometimes it takes a minute a two to lock onto 3 or more GPS satellites (you can see how many satellites are being received by selecting the Main Menu – Settings – GPS Diagnostics). If you continue to have problems getting a GPS satellite fix, please make sure that you are outside and the GPS antenna has a good visibility to the open sky. Some heat-reflecting windshields and built-in windshield heaters block the GPS signal reception inside the car.

The AMR meter is only activated when interrogated by a meter reader outside the home. The radio transmission is activated for only a fraction of a second per month. The radio transmission should not interfere with any other devices.

No, FORESIGHT device is highly immune to interference. CAT 5 UTP twisted pair wire can immunity the RF interference. The only concerned is high power (signal noise ratio) RF signal would have video interference occurred, neither coaxial nor twisted pair cabling transmission. You could try to use twisted pair wire with overall aluminum foil Mylar shield with one drain wire and braided shield. Or move away from high interference area.

The Golf Buddy can receive GPS signals from anywhere in the world. The Golf Buddy's satellites are the same satellites used by U.S Military, and the FAA is now in the process of using the same system as the primary navigation system for aviation. Generally it takes 1 or 4 minutes to receive the stable satellite signals in open-wide areas such as golf clubs.

Number of trackpoints that report a discrepancy between the distance reported and the location reported

The TSC program runs as a Low Priority process, using only idle cycles of your CPU. This means that it is designed to run in the background, and will yield CPU cycles to other applications. It will not interfere when you're using your PC for other things.

Profiles are added weekly, as we receive data from property managers, developers and other sources. Coming are thousands more profiles in suburban Cook County, starting with more than 400 in Evanston.

Answer: The GPS is the Genealogical Proof Standard, which all genealogists use to evaluate the quality of research and the reliability of conclusions. Question: Why don’t genealogists use the simple terms “primary source” and “secondary source”? In school I was taught to use these to decide whether sources were reliable. Answer: Determining reliability is not a simple matter.
