GPS Technology to Golfers Worldwide

SkyGolf, the developers of SkyCaddie, the1 rangefinder in golfing, and u-blox, the manufacturer of high performance consumer GPS receiver technologies, announce the development of TruePoint(TM) precision GPS technology in an exclusive cooperation to provide unprecedented accuracy for golfers.

The SkyCaddie(R) SG5 rangefinder uses GPS to answer the oldest question in golf, "how far?" , without needing markers or squandering time pacing off distances. It calculates distances automatically providing golfers with the information they should play over 17,000 golf courses at over 45 nations. The SkyCaddie is similar to having a professional caddie at the palm of the hand. SkyGolf's patented IntelliGreen(R) technology also permits golfers to assess the complete depth and shape of the green from any angle of approach and immediately compute distances to up to 40 goals at a time, helping golfers gauge distances to risks and pick the best club for their next shot.

At the heart of the SkyCaddie SG5's rich functionality is a custom-engineered GPS receiver from Swiss GPS receiver IP maker u-blox. A cooperative technology effort involving u-blox and SkyGolf led to the advanced positioning technology TruePoint(TM). In the SkyCaddie SG5, TruePoint(TM) provides placement accurate to under a meter and a supplementary time to first fix in a tiny, easy to use, hand-held apparatus with very low power requirements. This breakthrough technology provides dramatically more precise position calculations compared to traditional GPS receivers used in consumer GPS devices designed for less demanding applications like hiking, hunting, and boating. The positional jitter and drift, that are inherent to other GPS placement products and procedures, is virtually eliminated, leading to reproducible accuracy exceptional in consumer GPS devices.

"We have always provided superior GPS placement in our products and constantly strive to continue improving our products beyond these accessible to customers. We were looking for a high-precision, dependable GPS technologies for our newest golf rangefinder products to provide customers with of the enhancements technology could bring to their own match. We selected u-blox for their high performance GPS engine and experience, and incorporated u-blox specific receiver algorithms that culminated in TruePoint(TM) precision GPS. This new technologies, when used in combination with our high-precision golf course maps, gives golfers yet another level of precision improvement they need to play smarter, faster and have more fun," explained Richard Edmonson, CEO at SkyGolf.

The size of a mobile phone and weighing just in five ounces, the SkyCaddie SG5 is small enough to be worn on your belt just like a cell phone and offers a wide array of user-configurable options, intuitive menus and a rechargeable lithium battery for longer battery life.

"This innovative device is set to revolutionize golfing in years to come," explained Brad Sherrard, Vice President Sales at u-blox America, Inc. "The combination of SkyGolf's IntelliGreen technology, which provides consumers an eagle's view of this green and lots of instinctive functions, and u-blox' exceptionally precise and reliable GPS technologies, with its distinctive TruePoint(TM) precision GPS technology enables the SG5 to calculate distances with unmatched precision. This produces the SG5 the perfect companion for amateur and professional golfers alike."

What are we, Google?

What are we, Google?

His/her Google is broken.

What is the temperature of the environment that the Satellites operate in?

What is the temperature of a vacuum?
But here's a bit more detail, How do Satellites survive Hot and Cold Orbit Environments?

What is the temperature of the environment that the Satellites operate in?

I'm sure you know the answer - up to 3500F.

The question is, do you know what temperature is?

What is the temperature of the environment that the Satellites operate in?

Here's a simple experiment that you can do to learn first hand a little about space and temperature.

1.  Heat your oven to 212°F (100°C).
2. Place a pot of water on stove to boil.
3.  When water boils and oven has reached set temperature place your left hand in the oven for 5 seconds.
4.  Place your right hand in the pot of boiling water for 5 seconds.
5.  Compare results.
6. (Optional)  Post your findings here.

Please tell me that we are not going down this rabbit hole again.  We explain temperature and thermal transfer.  They feign surprise and terror about numbers that sound scary.  They claim we are lying about how thermal transfer works and say that the satellites would melt or freeze et cetra et cetra.  Round and round no ground given, facts vs feelings.  They feel like they are being lied to because they don't understand, we don't properly help them understand, we all dig our heels in.  Wasted effort all around.

As an expert in going down rabbit holes ...

Flag waving in vacuum
Shadows in different directions
Angular size of Sun/Moon

Mars the size of the Moon in the night sky


These will never go away

I'm sorry, but what does any of that have to do with space?

There is so little thermal mass there the question is irrelevant.
What is far more important is how much radiation are their absorbing and how much are they emitting.
This is balanced to keep them operating within suitable temperature ranges by controlling how much is absorbed and reflecting most radiation except that for solar power generation.

It is to show why discussing it in terms of "temperature" doesn't make much sense.
The oven is hotter than the water, yet due to the water's greater thermal mass and conductivity, it will transfer heat to you much faster resulting in much more damage.
So a satellite operating in an environment like a few thousand degree oven with almost no thermal mass or thermal conductivity will not damage it from the heat of the environment.

I don't know why so many words in this thread, it was a simple question. The temperature is 85 degrees Fahrenheit.

1.  Heat your oven to 212°F (100°C).
2. Place a pot of water on stove to boil.
3.  When water boils and oven has reached set temperature ...

The oven is hotter than the water ...

Why is an oven set at 100°C hotter than boiling water? Is the water at altitude? In space?

Flag waving in vacuum

Due to twisting motion while inserting and the vacuum not damping the motion.

Shadows in different directions

Due to both perspective and uneven terrain.

Angular size of Sun/Moon

Where is there a problem?

Curvature of horizon

Where's the problem? The shouldn't be any visible horizontal curvature of horizon at low elevations.

Mars the size of the Moon in the night sky

Presumability due to inability focus the camera properly on Mars.

What rabbit holes?

To get a comparison.
If you like, you can use a 100 degree oven.

And where did you pull that from?
Satellites operate in space in a region of varying temperatures. The tiny amounts of gas in the illuminated regions can get quite hot, but in the shade you drop to almost nothing

And where did you pull that from?

My ass.

Isn't that a requirement on this forum?
