The GPS (Global Positioning System) satellites are approximately 5.18 m across and transmit two low-power signals, one of which is at 1575.42 MHz (in the UHF band). In a series of laboratory tests on the satellite, you put two 1575.42 MHz UHF transmitters at opposite ends of the satellite. These broadcast in phase uniformly in all directions. You measure the intensity at points on a circle that is several hundred meters in radius and centered on the satellite. You measure angles on this circle relative to a point that lies along the centerline of the satellite (that is, the perpendicular bisector of a line which extends from one transmitter to the other). At this point on the circle, the measured intensity is 2.00 W/m^2
At how many other angles in the range 0 < theta < 90 is the intensity also 2.00 W/m^2?
Find the four smallest( positive) angles in the range 0 < theta < 90 for which the intensity is 2.00 W/m^2.
What is the intensity at a point on the circle at an angle of 4.65 degree from the centerline?

I am looking to buy a handheld GPS unit, and it needs to be a model that can be mounted on a bicycle. The bike is a road bike, but I want to make sure the GPS holder is secure and will not let the GPS be damaged. I would prefer a Garmin GPS (particularly the Nuvi) because the screen is larger. Do you have any suggestions where I can find a mount or what would be the best one to use? Thanks!

*The person I am shopping for rides a bicycle and is soon moving to a new city (and therefore will not be familiar with the area). I want something that can not only be used on a bicycle, but also in a car.

This Grip Pod System (GPS) demonstration video is brought to you by DefenseReview.com, courtesy of Chen Lee aka “SMGLee”. As the video demonstrates, the Grip Pod System (GPS) is a combination vertical foregrip/fast-deploy weapon stabilization device/bipod that provides the operator with greater combat capability and versatility for his carbine, rifle, or SBR (Short Barreled Rifle) by allowing him to go prone in an instant and continue fighting from a stable platform. The Grip Pod’s spring-loaded bipod/weapon stabilization system deploys instantly with the push of a button by either your thumb or index finger, depending on how you have the Grip Pod oriented on your rail (activation button facing backward towards you, or forward away from you). While the Grip Pod System GPS02 military model weighs only 7 ounces (7 oz), it was designed and developed specifically for military combat and hard use, so it’s made from advanced, reinforced polymers with stainless steel inserts for the fast-deploy legs. The Grip Pod System GPS01 model is the LMG/SAW (Light Machine Gun / Squad Automatic Weapon) version, and it’s made from 7075-T6 Aluminum with a mil-spec hard coat finish. It weighs 11 ounces (11 oz). The Grip Pod has been adopted by the US Marine Corps (force-wide) and the US Army. It’s the best, fastest, and most versatile weapon stabilization platform for the M4/M4A1 Carbine and M249 SAW.

I have a Magellan Explorist GPS, and I accidentally left it on the dash of my car for an hour in the sun. Now when I turn it on, the numbers are still nice and clear, but the graduated grays are gone. I have black and white, no grays. Any way to fix it? Maybe put it in the freezer for an hour? *laughs*
This video forms part of a webinar on ‘How to use GNSS Record and Replay to make your testing faster and more effective’. It is essential viewing for anyone who tests and develops GNSS devices, and the recording is available on www.labsat.co.uk
