  2. LOW LATITUDE IONOSPHERIC SENSOR MAGNETOMETERS NETWORK • Outline • Network Deployement and Installation • LISN Magnetometers description • Magnetometer Operational Status • Preliminary Results • New developments and Conclusions Second LISN Workshop, San Jose Dos Campos, Nov 07-11, 2011

  3. LOW LATITUDE IONOSPHERIC SENSOR MAGNETOMETERS NETWORK • Outline • We describe here the present status of the LISN magnetometer network operation and data collection. • Five triaxial magnetometers were deployed and installed since 2007 at Leticia-Colombia (2009), Puerto Madonado-Peru(2007), El Leoncito-Argentina (2008), Cuiba-Brasil (2010), Alta Floresta-Brasil (2010) • New magnetometers developments and improvements plans for upgrading the existing IGP and LISN magnetometers

  20. Data Collection (Sep. 9-10, 2011

  21. LISN Magnetometer System Hardware Development • The experimental considerations of the current magnetometers in operation have led us to develop and construct a new high performance fluxgate magnetometer at Jicamarca. • Internal GPS has been incorporated for precisely and timing software controlled of the overall magnetometer operation. • We describe also a development plan for a new data acquisition system based on embebed and stand alone system which is being carried out at IGP.

  25. Conclusions and Recommendations • Five magnetometres are operating in near real time. • There are some data gaps in the reported data due to logistical problems such as Internet and lost of data due to stations AC power outages or PC fails. • It is recommended to have a periodical stations maintenance and calibrations at least once a year • Upgrade the existing LISN magnetometers network with the new developed magnetometers • Improve the logisic and communications beetwen operators
