Zunibal Drifting Buoy Z-Sphere (SVP)

Manufacturer: Zunibal

Availability: Usually ships in 1 week

Z-Sphere is a small and compact drifter marker buoy, can also be used as a Surface Velocity Program (iSVP) drifting buoy, it is equipped with bi-directional Iridium satellite telemetry which, when coupled with back-office data presentation services such as those offered by ZUNIBAL, provide the user with real-time data location and tracking information, essential for SAR and spill tracking operations. The new Z-Sphere is powered by solar cells which means the running time is theoretically unlimited.

The Z-Sphere mini Buoy is a small and compact tracking & monitoring buoy based on Iridium satellite system. This buoy can be tailored to suit a wide range of applications as surface drifter to track sea currents, oil spills and rescue operation between others. It can also be used as a Surface Velocity Program (SVP) drifting buoy.
The Surface Velocity Program (iSVP) drifting buoy is a Lagrangian current-following drifter, designed to track water currents (15 metres depth) beneath the ocean surface.
The modern drifter is a high-tech version of the "message in a bottle". It consists of a surface buoy and an optional subsurface drogue (sea anchor), attached by thin tether. The buoy measures temperature and other properties, and has a transmitter to send the data to passing satellites.

Z-Sphere OVERVIEW

  • The Z-Sphere satellite-tracked surface drifting buoy ("drifter") is a low-cost small oceanic Lagrangian device to track sea currents based on Iridium communication network.
  • The position is obtained by a GPS module, and it has a IRIDIUM satellite data transmission system.
  • The Iridium® modem provides the end-user with lower transmission costs and an increase in data throughput.
  • The sampling frequency and transmission frequency are configurable by Zunibal before ordering or later in remote mode.
  • The Z-Sphere has a small diameter, only 31,2 cm and its low weight of 7,5 kg makes the whole system very user freindly for deployment and recovery.
  • Its 14,6 liter volume allows the use of a SVP´s holey sock drogue.
  • Its solar rechargeable energy system makes the running time theoretically unlimited.
  • The Z-Sphere accurately follows near surface currents and can be rapidly air/vessel deployed for Search & Rescue operations or to track spills etc.
  • The standard measurements are water temperature, GPS position/time and battery level.
  • The buoy is equipped with a highly reliable magnetic switch
  • Fully plastic buoy with a rubber protection around it for impacts absorption.

SURFACE VELOCITY PROGRAM (SVP)

The Surface Velocity Program (SVP) drifting buoy is a Lagrangian current-following drifter, designed to track water currents (15 metres depth) beneath the ocean surface. Developed for unattended operation in the oceans of the world, the SVP consists of sensors to acquire meteorological and oceanographic data, a battery power source, and a satellite transmitter that relays the data through Iridium® satellite systems.
The standard SVP is equipped with a sea surface temperature sensor. The SVP’s holey sock drogue is centered at 15 meters and is sized to provide a drag ratio (drogue frontal area to that of all other submerged frontal areas) in excess of 40:1.
Additional sensors can be added. They include; barometric pressure (BP), salinity, and conductivity. The SVP buoy has been a proven data collection asset for the oceanographic, meteorological, and oil and gas markets.
