GPS Receiver

Additional Comments
This receiver is PC or handheld based. It has software that comes with it and stores data on the computer in a proprietary format. Free software on the web enables the transformation from the proprietary format to.txt or other more universal formats. Uses the SiRF Star II chipset, which has proven to be very accurate. Has no magnetic mount. (www.delorme.com)

GPS-16 (HVS)

This receiver connects to a PC, handheld, or PA monitor/controller. It comes bare wired, so installation requires added skill. It tends to be less mobile. It has a 1 Hz update rate which isn't fast enough to run a lightbar with the accuracy needed at the speed of most agricultural operations. HVS stands for low voltage system. It operates at a higher voltage range than the LVS. (www.garmin.com)

GPS-16 (LVS)

This receiver connects to a PC, handheld, or PA monitor/controller. It comes bare wired, so installation requires added skill. It tends to be less mobile. It has a 1 Hz update rate which isn't fast enough to run a lightbar with the accuracy needed at the speed of most agricultural operations. LVS stands for low voltage system. It operates at a lower voltage range than the HVS. (www.garmin.com)

GPS-16 A

This receiver connects to a PC, handheld, or PA monitor/controller. It comes bare wired, so installation requires added skill. It tends to be less mobile. It has a 5 Hz update rate which is fast enough to run a lightbar with an accuracy of only < 3 m (even with WAAS). (www.garmin.com)

GPS-17N

This receiver connects to a PC, handheld, or PA monitor/controller. It comes bare wired, so installation requires added skill. It tends to be less mobile and becomes a more permenantly installed receiver. It has a 1 Hz update rate which isn't fast enough to run a lightbar with the accuracy needed at the speed of most agricultural operations. It operates at a higher voltage range, similar to the GPS-16 (HVS). (www.garmin.com) This receiver connects to a PC, handheld, or PA monitor/controller. It comes bare wired, with a USB connection, or with a 9-pin RS-232 connection. It tends to be less mobile and becomes a more permenantly installed receiver. It has a 1 Hz update rate which isn't fast enough to run a lightbar with the accuracy needed at the speed of most agricultural operations. It is one of the most inexpensive receivers on the market, and would be perfect for yield monitoring. (www.garmin.com)

GPS-18

GPS 60 C/CS
Garmin's newest handheld. In addition to adding color, new geocaching and auto-routing features have been added. The CS version also contains a barometer/altimeter combo and an electronic compass. (www.garmin.com)

Rino 110

Offers two-way radio feature using the family channels (2 mile range) as well as GRMS (5 mile range - requiring FCC license). Transmits position by the radio feature which is then plotted on other Rinos. (www.garmin.com)

Rino 120

Offers two-way radio feature using the family channels (2 mile range) as well as GRMS (5 mile range - requiring FCC license). Transmits position by the radio feature which is then plotted on other Rinos. Also has substantial memory for data storage. (www.garmin.com)

Global Sat

SD-501
One of two SD-type receivers now available. Compact Flash (CF) style insertable receivers have simplified PDA/GPS combinations. This may provide a viable alternative for those who have PDAs that have no CF slot and only a SD slot. The additional apparatus on the top is suppose to aid satellite reception, but appears to increase the opportunity for damage. Accuracy is apparently its advantage. (www.globalsat.com.tw) A receiver/antenna combination that is based on the same chipset, the SiRFstarII chipset, as many other products. Has a magnetic mount to easily and safely lay on top of equipment or vehicle. Has PS2 connection (like the connection used for mouse and keyboards) but connects to USB or 9-pin serial (RS 232) cable adapters that can be specified with the kit. (www.holux.com)

GM-210

GM-270
A CF-based GPS that uses the SiRFstarII chipset. (www.holux.com)

GM-270 Ultra

According to the spec sheets, the GM-270 Ultra is a more sensitive receptor of weak satellite signals, especially those that occur in densely wooded areas. (www.holux.com)

GR-230

A bluetooth (wireless) receiver. Uses SiRFstarII chipset. Is quoted as a 33ft. range in the Bluetooth. (www.holux.com)

Lowrance

iFinder Series
Also known for their development of recreational marine electronics, Lowrance provides a sturdy line of user friendly GPS receivers. Unfortunately, data on the accuracy of these devices is lacking from their website and other sources used. (www.lowrance.com)

Magellan

eXplorist 100/200/300
This is Magellan's venture into the lower, inexpensive end of the GPS spectrum. Their low price is attractive, but like Garmin's Geko 101, they lack the essential ability to stream NMEA protocol strings. The 100 has no integral memory, while the 200/300 series offer 8 MB. The 300 adds the extra functions of a barometer/altimeter and electronic compass. (www.magellangps.com)

Meridian Color

Offers great deal of expandability by using a SD cards (www.magellangps.com)

Meridian Gold

Meridian Marine

Meridian Platinum

SporTrak

SporTrak Color

SporTrak Map

SporTrak Pro

SporTrak Pro Marine

SporTrak Topo

This is a relatively new offer from Magellan. It has not yet been priced as it will not be on the market until Nov. 2003. (www.magellangps.com)

Navman

GPS 110
This is Navman's entry into the receiver/antenna combination. Priced competitively with other such devices. Uses a Conexant Zodiac chip set system without WAAS correction (apparently). The connection with the laptop, PDA or other such device isn't explicit in the spec sheet, either. (www.navman.com)

GPS 3450

Sleeve GPS for iPAQ. Uses SiRFstarII chipset. (www.navman.com)

GPS 4400

A bluetooth (wireless) receiver. Uses SiRFstarII chipset. Is quoted as a 33ft. range in the Bluetooth. (www.navman.com)

NavRoute

HP-505/525
A receiver/antenna combination that is based on the same chipset as others products from NavRoute and other companies, the SiRFstarII chipset. Has a magnetic mount to easily and safely lay on top of equipment or vehicle. (www.navroute.com)

HP-600/610

A CF-based GPS that uses the SiRFstarII chipset. (www.navroute.com)

HP-700

A bluetooth (wireless) receiver. Uses SiRFstarII chipset with FoliageLock to compensate for weak signals. (www.navroute.com)

Pharos

SDIO GPS
One of two SD-type receivers now available. Compact Flash (CF) style insertable receivers have simplified PDA/GPS combinations. This may provide a viable alternative for those who have PDAs that have no CF slot and only a SD slot. This one seems to be more "low-profile" than the SD-501, which could aid its ruggedness in the field. But, early indications are that it is not as accurate as the SD-501. (www.pharosgps.com)

Rayming

A CF-based GPS that uses the SiRFstarII chipset. Most likely the same receiver as the NavRoute version. (www.rayming.com)
A bluetooth (wireless) receiver. Uses SiRFstarII chipset with FoliageLock to compensate for weak signals. Again, most likely the same receiver as the NavRoute version. (www.rayming.com)
