Topcon Announces GRS-1 Hand-held GNSS Rover System
Topcon Positioning System’s (TPS) new GRS-1 (Geodetic Rover System) is the first fully integrated dual-constellation, network-enabled RTK rover system. It is an all-in-one handheld GNSS receiver and field controller with high-speed processor, increased memory, built-in camera, compass and bar code reading function.
Features also integrated into the new system are an SD memory card slot, optional internal GSM or CDMA modem, and wireless connectivity via Wi-Fi and Bluetooth technology.
The GRS-1 was designed with two primary system design goals: Smaller size and weight, and lower-than-expected cost. According to Mark Contino, vice president of survey and GPS sales, the GRS-1 “packs all the power of a full GPS + GLONASS dual-frequency receiver, cellular modem and Windows PC into a very small, very powerful package.”
Designed primarily as a GPS network rover receiver, the GRS-1 “provides a small, lightweight rover and a price to fit any budget,” he said. “The new receiver has DGPS capability with an internal L1 antenna for GIS and navigation. Add the PGA-1 external antenna and connect to your local GNSS network via the internal modem, and instantly move to dual frequency, dual constellation GNSS centimeter RTK accuracy. The GRS-1 can also be used as a static post processed receiver system.”
The GRS-1 uses the Windows Mobile 6.1 operating system to run TopSURV, Topcon’s popular surveying software. TopSURV 7.2 adds new features and functions that are unique to the GRS-1. The receiver and field controller also has a 3.7-inch, touch screen display and its rugged construction is rated to stand a one meter drop.
In addition to the network rover configuration, the GRS-1 also has an optional RH-1 radio module that can be configured to work with existing Topcon GNSS receiver systems that are already in the market today. The RH-1 is available in digital UHF, spread spectrum and frequency channel scan UHF varieties.
All forms of radio correction that current and legacy Topcon GPS+ systems offer are supported within the RH-1 module of the GRS-1 system. This means that if a customer purchased a previous system from Topcon they can be backwards compatible.
“With the GRS-1 network rover, no additional modem or equipment is needed . . . it’s all built in. The user can access an RTK network for sub-meter to sub-foot mapping. By attaching an easy-to-connect external antenna, centimeter accuracy is instantly achieved,” adds Contino.

Neuwaukum Industries Introduces Hard Hat Safety Mirrors At World of Asphalt
Each year, more than 100 workers are killed and over 20,000 are injured in the highway and street construction industry. Vehicles and equipment operating in and around the work zone are involved in over half of the worker fatalities in this industry.
Often these accidents leave tragedy in their wake. On October 18, 1999, Kim Vendl was killed when a dump truck, moving about 5 mph, backed over her without any warning. In response, WAC 296-155-305 was born, which recommends using hardhat mounted rear-view mirrors “to warn and protect…from traffic and equipment approaching from behind.”
Neuwaukum Industries, Inc. (NII), became a front-runner in this campaign to save lives and reduce injuries by introducing the GOBLIN Hard Hat Safety Mirror. Designed for anyone wearing a hard hat, these mirrors expand the wearer’s peripheral vision zone and greatly improve safety in the work zone.
On November 17, 2008, after two years of research and development, NII introduced the GOBLIN Hard Hat Safety Mirror. Designed by a team of award winning engineers, safety specialists, and materials experts, this project grew out of the necessity for “active” safety gear to reduce construction work zone injuries and fatalities.
Currently the methods used to prevent injuries and fatalities, due to run-overs and back-overs, consist of back-up alarms, rear view cameras, safety vests, jersey barriers, and observers. None of these methods give people on the jobsite, in danger, the ability to see for themselves what is going on around and behind them.
GOBLIN Hard Hat Safety Mirrors are a low-cost solution that provides an expanded peripheral vision zone. The added peripheral awareness, up to 180 degrees, gives the wearer an active/offensive advantage over their environment. They are lightweight, adjustable mirrors that clip easily to the brim of most hard hats and do not hinder forward vision. Used in pairs, they stay virtually invisible to wearers until danger approaches. Now, in addition to other passive safety measures, the wearer is actively involved in his/her own safety.
Built to hold up in a tough environment, each GOBLIN is made of industrial-grade, non-conductive plastic. The mirrors are scratch-resistant and tinted to prevent glare. In the event of a hard impact, a unique “breakaway” system allows individual parts of the GOBLIN to safely separate from each other, preventing wearer injury. GOBLIN Hard Hat Safety Mirrors were designed to meet ANSI and Washington Administrative Code 296-155-305 standards.
According to representatives from NII, “ World of Asphalt 2009 was a major success for NII and Goblin Hard Hat Safety Mirrors! The “GoblinEffect” swept through the trade show floor and created believers out of everyone including representatives from DOT’s, OSHA, ARTBA, FHWA, Lane,
Granite, Lafarge, APAC and large construction companies from 16+ other countries…and the list goes on!”
BOMAG Introduces Economizer System At ARA
BOMAG’s exclusive Economizer system helps contractors complete compaction jobs more quickly and effectively, saving time, fuel and money. The Economizer system is a standard feature on the BOMAG BPR100/80D reversible vibratory plate compactor. It is an option on the BPR45/55D series, BPR55/65D and the BPR65/70D.
