Sarantel’s revolutionary ceramic filtering antennas offer dramatically improved performance over existing antenna designs, resulting in a clearer signal, better range and a 90 per cent reduction in the amount of signal radiation absorbed by the body.
Sarantel confirms volume production orders
Specialist antenna firm Sarantel (LON:SLG) has confirmed today that the volume production orders for its GeoHelix GPS filtering antenna announced in mid-May were for the AutoSeis HDR1C – an autonomous, high-definition recording unit (otherwise known as a ‘node’).
The AutoSeis HDR1C is supplied by AutoSeis Incorporated, a global geophysical services company. According to Sarantel, the HDRC1C seismic node “promises to revolutionise the natural resource exploration process”.
The node uses Sarantel’s GeoHelix GPS antenna as part of a precision timing and location system that enables the probe to gather highly-accurate geological survey data.
The GeoHelix GPS antenna was selected for the application because it offers an omni-directional gain pattern that provides the customer with stable and reliable GPS performance across a wide range of installation environments.
The wireless capability of the HDRC1C means that many of these nodes can easily be deployed over a large geographical area, replacing expensive and time-consuming wired survey systems. This means, as Sarantel said back in May, that the deal should “have a material impact on revenues” over the next year.
“Selection of our technology by AutoSeis underscores the progress we are making in delivering leading edge solutions,” said David Wither, Sarantel’s chief executive officer. “GPS is used as a precision timing source for a broad range of applications and the HDR1C autonomous seismic node is a great example of how our technology is enabling the development of a raft of game changing devices.”
Shares in Sarantel were higher by 3.7 per cent at 0.7 pence each soon after the market opened this morning.
