One of the most useful technical developments of recent years allows folks to use satellite signals to determine precisely where they are. A leading maker of the devices that accomplish that bit of magic is headquartered in Sunnyvale, California.

Trimble Navigation (NASDAQ: TRMB) provides advanced positioning products and services to commercial and government users in the surveying, construction, agriculture, resource management, military, transportation and telecommunications markets. Essentially, the firm makes navigation systems and software based on the US government-owned global positioning system (GPS) satellite network. It also makes devices that track ground vehicle and aircraft fleets, as well as timing devices that synchronize communications equipment. Customers include Caterpillar (NYSE: CAT) and Nortel Networks (NYSE: NT).

The company surprised the Street last week, when it reported Q2 EPS of 35 cents and revenues of $327.7 million. Analysts had been expecting 30 cents and $311.4 million. The CEO attributed the good results to growth across all segments, particularly on the international side. Management also guided Q3 EPS to 26-28 cents (26 cent consensus) and Q3 revenues to $294-$299 million ($292.17M consensus). Needham, Dougherty and Soleil subsequently declared the stock a "buy." The share price popped on the news and has since been consolidating the gain in a bullish "pennant" pattern. Prices frequently exit pennants moving in the same direction they were traveling when they entered them. In this case, that would be to the upside.

Altogether, brokers now recommend the issue with six "strong buys," three "buys" and two "holds." Analysts expect a 21% growth rate through the next year. The TRMB Price to Free Cash Flow ratio (29.96), Sales Growth rate (33.59%), EPS Growth rate (25.00%) and Return on Assets (9.60%) compare favorably with industry, sector and S&P 500 averages. Institutional investors hold about 86% of the outstanding shares. The stock is one of those used to calculate the S&P 600 SmallCap Index. Over the past twelve months, it has traded between $21.45 and $39.02. A stop-loss of $33.25 looks good here.

According to the German magazine Focus and reported on MacRumors.com, Apple Inc (NASDAQ: AAPL) is reportedly looking at developing a car navigation and sound systems. The device, which would combine navigation, entertainment and communication in a single unit, would be introduced in 2009. Apple is said to be working with Mercedes, which may hold exclusive rights for six months once released. It is unclear if Apple will rely on Google Inc's (NASDAQ: GOOG) Google Maps for help with navigation.

Sources speculate that an Apple's device would be similar to ones already on the market. Apple has long been known to rise above its competitors. Some say the upcoming iPhone may clean up, so it may not be a stretch to say that a navigational device has the potential to do the same.

Who would be affected by a navigational device from Apple? Here's the competition:

• Garmin Limited (NASDAQ: GRMN): Garmin is a worldwide provider of navigation and information devices, many of which are enabled by global positioning system technology. Last week, Garmin International announced the nuvi 200W and the nuvi 250W, two new widescreen GPS navigators. With a 4.3-inch color touch screen display and a high-sensitivity internal GPS antenna, the question is, can it trump whatever Apple does?

• Trimble Navigation Limited (NASDAQ: TRMB): Trimble provides advanced positioning product solutions, typically to commercial and government users. Last month it received an $8.8M purchase order from the U.S. Marine Corps and signed an agreement with Cox Communications. How formidable a competitor would Apple be?

• SiRF Technology Holdings Inc (NASDAQ: SiRF): SiRF is a supplier of GPS semiconductor solutions, offering a wide-range of GPS chip sets and other products for high-volume markets. Earlier this month, the company announced SiRFDiRect technology, what they touted as a "navigation breakthrough." Could Apple steal their thunder?
