* Rev up 8 pct
* Gross margins $6.6 mln vs $7.3 mln yr ago
Aug 10 (Reuters) - Hemisphere GPS Inc HEM.TO, a Canadian maker of GPS products for agriculture, marine and other markets, posted a wider quarterly loss, mainly due to negative foreign exchange volatility and tepid grain prices.
For the second quarter, net loss was $1.9 million, or 3 cents a share, compared with a loss of $1.3 million, or 2 cents a share, a year ago.
Revenue for the company rose 8 percent to $15.6 million. Sales of ground agriculture products were up 10 percent.
Analysts on average were expecting a profit of 1 cent a share, on revenue of $17.3 million, according to Thomson Reuters I/B/E/S.
Hemisphere GPS, which competes with companies like Trimble Navigation Ltd (TRMB.O) and Canada-based NovAtel Inc, said margins fell year over year mainly as a result of the impact of the weakening of the U.S. dollar and program-related pricing discount.
The latest quarter gross margins of $6.6 million were down from $7.3 million, last year.
