LXNAV S10 and S100 Variometers with GPS Flight Recorder
The S10 and S100 are very powerful and full-featured speed-to-fly variometers with navigation, IGC Approved GPS flight recorder with Engine Noise Level sensor, built-in back-up battery, built-in Bluetooth, and built-in AHRS (optional software enable). The S10 fits into a standard small 57mm instrument hole. The S100 fits into a standard 80 mm instrument hole. Other than the size of the display, the S10 and S100 are functionally identical - the screens even have the same number or pixels. They can display waypoints and airspace and can be used to navigate to waypoints and around tasks. They can display final glide information and shows turn areas on the moving map. They have an extremely powerful processor and use a MEMS inertial platform and pressure sensors. The built-in 320 x 240 pixel color displays are used to display parameters such as vario average, thermal average, distance to goal, altitude, battery level, speed-to-fly push/pull indicator, MacCready setting, etc. 

NEW Option - HAWK Vario, Winds, and AHRS

Features:

• HAWK’s blue vario pointer is fast and closely matches the lift you feel in the seat of your pants.  
• Better than any other vario - ever!
• Ignore fake thermals caused by gusts
• How many times has this happened to you:
• You’re cruising. 
• You feel a bump.
• The red Total Energy vario pointer goes up.
• You stop to circle and find no usable lift. 
• It’s not a thermal.  It’s a gust.
•  With HAWK:
• The blue HAWK vario pointer remains flat.  HAWK knows it’s a gust!
• Never again waste time stopping to try a “thermal” that is really a bump from a gust.
• Greatly increase your cross-country speed (worth every penny of price)
• Know exactly what the wind is doing in real-time
• HAWK software uses accelerometers and GPS for:
• Fast vario which ignores horizontal gusts
• Fast wind data for optimizing flight in convergence and wave
• AHRS

The HAWK and AHRS sensors are built-into all V9, V8, V80, S10 and S100 varios. To use the HAWK Wind and AHRS functionality it is necessary to purchase this software enable key. The artificial horizon and airspeed and altitude items can be setup to display on any page on the LX80X0 or LX90X0 display using the LXStyler program - or using the controls on the flight computer. The artificial horizon also displays on the V8 and V80 vario's display and on the S10 and S100 vario's display.

Details are available in the LX80x0 or LX90x0 or S10, or S100 manual which is available here.

"Are you dreaming about having a real time wind indication in your glider? Do you feel sometimes in the mountainous regions or areas of convergence that the wind suddenly changes?”

Get real-time wind with HAWK
Real-time wind indication – 3D wind. HAWK option enables instantaneous wind readings on all 3 axes.

Measurement
HAWK uses sensor fusion and advanced digital signal processing to estimate the air mass movement.

3-dimensional wind triangle
HAWK applies an “extended Kalman filter” (EKF) algorithm that jointly estimates all three dimensions of the air mass movement.

Instant results
EKF estimates the wind direction and velocity instantaneously (horizontal and vertical). No more waiting!

No compensation, no compromise
No compensation needed, since it uses no law of energy conservation. More accurate netto vario readings independent of glider speed.
No false thermals due to wind gusts = No more “stick” lift.

Wind indication
Wind screen enables you to view the instantaneous wind on the blue arrow and the wind average on the white arrow .

2 needle vario
A red and blue vario needles at the same time. Red shows the value of computations of the TEK while light blue shows the value of the EKF.

AHRS
The results of the attitude estimate of the EKF can also be displayed as an artificial horizon.

One of 100+ videos in the Soaring Product Training series

I am especially impressed with the way the vario 20 second average (red diamond), MacCready (blue triangle) and Thermal Average (green "T") are displayed on the vario scale - making it easy to compare the MacCready setting to the thermal average, 20 second vario average, and instantaneous vario reading (red pointer).  Another interesting feature is that a yellow arc is displayed around the inside of the variometer scale which indicates the maximum and minimum lift lift/sink rates over the last 20 seconds.  That will be useful while centering thermals and deciding when to leave a thermal.  Alternatively, the red diamond and yellow arc can be configured to display g-meter instantaneous and min and max readings. The g-meter can be reset manually and it automatically resets on take-off. A built-in logbook feature is also very nice.  It makes it easy to update your personal of sailplane logbook with dates (if a GPS is connected) and flight times. The S8 can provide 5V power for a PDA or PNA.

Easy and Fast Flight Log Downloads
Since a microSD memory card slot is built-into the face of the vario, it is easy to transfer flights to the memory card and take them home at the end of the day. Flight logs are transferred in a second or 2 using the logbook screen. Firmware upgrades are also done using the built-in microSD memory card reader. Waypoint, airspace and FlarmNet files are also loaded using the memory card slot.

The Perfect Replacement for an ILEC SN10 or Cambridge 302/303 or L-NAV or S-NAV
The S10 and S100 are great replacements for the ILEC SN10 or Cambridge 302/303 or L-NAV or S-NAV flight computer. The S10 and S10 make the older products look obsolete and are much easier to connect to external products like a PowerFLARM and/or Naviter Oudie. Alternatively, those same instruments can be neatly replaced with an LX8080 and V9 or V8 vario. The LX8080 and V9 or V8 vario do everything the S8 and S80 do, but can also display terrain data on the moving map.

AHRS
The LXNAV-AHRS-Enable (artificial horizon) is an extra cost software option (see pricing at right). It is enabled by purchasing an enable code for your particular S10 or S100. The AHRS sensor hardware is installed in every S8 and S80. The upgrade can be purchased from Cumulus Soaring, Inc. at the time you purchase the S8 or S80 or anytime afterward. The enable code is tied to the unit's serial number.

Flying Modes
Note: The vario ring around the outside of the screen is visible in all the flying modes. It is easy to rotate through the flying modes using the center button on the right side of the unit.

• Status Mode - GPS status, etc.
• FLARM Mode
• Thermal Assistant Mode
• Waypoint Navigation Mode - This screen displays waypoints and airspace (no terrain) and can be used to navigate to a waypoint. FLARM and other traffic is also displayed on this screen. Use the top and bottom push-buttons to cycle through the 3 screens in this mode: Map, Vario, AHRS (if enabled). The vario screen is the black screen shown at right which includes 4 data windows and many other small displays - such as GPS status, vario units, cruise/climb mode indicator, etc.
• Task Navigation Mode - This screen displays waypoints, tasks, and airspace (no terrain) and can be used to navigate around a task. FLARM and other traffic is also displayed on this screen. Use the top and bottom push-buttons to cycle through the 3 screens in this mode: Map, Vario, AHRS (if enabled). The vario screen is the black screen shown at right which includes 4 data windows and many other small displays - such as GPS status, vario units, cruise/climb mode indicator, etc.

IncludedS10 or S100 variometer

• GPS Antenna
• microSD memory card
• Printed manual (printed by Cumulus Soaring, Inc.)
• Wiring harness with 12V power connections, outside air temperature probe, digital inputs and RS-485 connector

Optional

• External GPS or FLARM Cable (select from several types - see note above)
• PDA Cable (select from several types - see note above)
• LXNAV-AHRS-Enable
• Stick-mounted Remote Control
• LXNAV-Compass-CANbux

Example System Configurations
The S10 and S100 are designed to work with or without connection to a FLARM and/or PDA.  That is nice for customers on a budget because you can buy the S10 or S100 now and add a FLARM and/or PDA later when you can afford to.

• 
  S10 or S100 Alone
  When you use the S10 or S100 alone (without a FLARM or PDA) it functions as a very nice speed-to-fly variometer with GPS flight recorder and navigation to waypoints and around tasks - with final glide calculations. It does not display terrain maps. It also features a very nice Thermal Assistant.
  
  
• 
  S10 or S100 with Oudie
  When connected to a Naviter Oudie the S10 or S100 sends GPS, vario, and airspeed and wind data from the S10 or S100 to the Oudie. The Oudie's Thermal Assistant is much more useful when connected to a vario. Also, the S10 and S100 can use airspeed and GPS data to calculate wind speed and direction while thermalling, and while cruising in wave or along a ridge. Official task declarations can be sent from the Oudie to the GPS flight recorder in the S10 or S100.
  
  
• 
  S10 or S100 with FLARM and Oudie
  A complete flight computer system includes a FLARM, the S10 or S100 variometer, and an Oudie running SeeYou Mobile soaring flight software.  In this case the S10 or S100 receives FLARM data from the FLARM and adds GPS, airspeed, wind and variometer data and sends it on to the soaring flight software in the Oudie.  Depending on the features of the soaring software you use, parameters like MacCready and Bugs can be exchanged between the S10 or S100 and the Oudie.  Official task declarations can be sent from the Oudie to the GPS flight recorder in the S10 or S100.
