The FAA’s New Drone Rules Are Effective Today | August 29th, 2016

The Federal Aviation Administration’s (FAA) new comprehensive regulations go into effect today for routine non-recreational use of small unmanned aircraft systems (UAS) – more popularly known as “drones.”


The provisions of the new rule – formally known as Part 107 – are designed to minimize risks to other aircraft and people and property on the ground. A summary is available here.

The FAA has put several processes in place to help you take advantage of the rule.

Waivers: If your proposed operation doesn’t quite comply with Part 107 regulations, you’ll need to apply for a waiver of some restrictions. You’ll have to prove the proposed flight will be conducted safely under a waiver. Users must apply for these waivers at the online portal located at www.faa.gov/UAS

Airspace Authorization: You can fly your drone in Class G (uncontrolled) airspace without air traffic control authorization, but operations in any other airspace need air traffic approval. You must request access to controlled airspace via the electronic portal at www.faa.gov/UAS, not from individual air traffic facilities.

You may submit your requests starting today, but air traffic facilities will receive approved authorizations according to the following tentative schedule:

Class D & E Surface Area                  October 3, 2016         
Class C                                               October 31, 2016       
Class B                                               December 5, 2016      

We will try to approve requests as soon as possible, but the actual time will vary depending on the complexity of an individual request and the volume of applications we receive. You should submit a request at least 90 days before you intend to fly in controlled airspace.

Aeronautical Knowledge Test. Testing centers nationwide can now administer the Aeronautical Knowledge Test required under Part 107. After you pass the test, you must complete an FAA Airman Certificate and/or Rating Application to receive your remote pilot certificate at: https://iacra.faa.gov/IACRA/Default.aspx

It may take up to 48 hours for the website to record you passed the test. We expect to validate applications within 10 days. You will then receive instructions for printing a temporary airman certificate, which is good for 120 days. We will mail you a permanent Remote Pilot Certificate within 120 days.


The new regulations don’t apply to model aircraft operations that meet all the criteria specified in Section 336 of Public Law 112-95 (which is now codified in part 101), including the stipulation they be operated only for hobby or recreational purposes.

Now Available: Trimble TerraSync Software Version 5.86 and Trimble GPS Pathfinder Office Software Version 5.85



New versions of Trimble® TerraSync™ field software and Trimble GPS Pathfinder® Office software have been released. This is a maintenance release which contains fixes for a number of support issues that have been reported.

End-of-Life Notice: Trimble Juno 3B Handheld


The Trimble® Juno® 3B handheld is to be discontinued and will only be available while stocks last. It is anticipated the available inventory of the Juno 3B will be exhausted by the end of Q3 2016.

The Juno 3 series handhelds have been replaced by the new TrimbleTDC100 series handheld.

Trimble TDC100 Series Handheld


As announced at the recent 2016 Esri User Conference in San Diego, Trimble is pleased to introduce the Trimble®TDC100 series handheld—an all-in-one professional data collector and smartphone.

Available with Android OS, the TDC100 addresses the limitations of consumer-grade smart devices when used for GIS applications to deliver an accurate data collection and asset management solution that works perfectly in situations where traditional BYOD mobile phones can't. 

Designed for mapping and GIS professionals working in a variety of industries, such as environmental management, public works, and utilities, the TDC100 empowers the mobile workforce with a fully integrated, GNSS-based data collection system for everyday field work.

SETTING ISO AND SHUTTER SPEED FOR THE UX5 SONY A7R CAMERA


Products affected

Trimble® UX5 aerial imaging rover

Summary 

How do I select ISO setting and shutter speed on a SONY A7R camera to obtain the best pictures?

Answer 

ISO

● The ISO is set automatically: the camera decides which ISO value to choose, based on the incoming light from the scene.

● The base ISO is 100, the maximum ISO is 6400, using ⅓Ev increments. Note: The camera can theoretically go up to ISO 25600. The limit is set to 6400 to avoid noise and effects of noise reduction that lead to an unacceptable loss of image quality.

● You do not need to change the ISO range between different lenses.

Shutter Speed The shutter speed should be as slow as possible, to gather more light so that the ISO (and resulting noise) can be kept to a minimum.

Since shutter speed is the only means available to counteract (forward) motion blur, there is a practical lower limit to the shutter speed. The rule of thumb to prevent forward motion blur is that the forward motion of the camera over the ground during the exposure time should never exceed 0.75 * GSD.

Additionally, we use an absolute minimum shutter speed of 1/1000 regardless of GSD to minimize other kinds of motion blur, when forward motion blur is not a risk factor in case of coarse GSD.

Example 1

When using the 15 mm lens at 120 m AGL, meaning 3.8 cm GSD, we could in theory use 1/800 to prevent forward motion blur (the aircraft moves 2.9 cm over the ground during the exposure time of 1/800 of a second at the nominal cruise speed of 23 m/s, which is less than 0.75 * 3.8 cm), but we will resort to the minimum "safe" shutter speed of 1/1000 to minimize other forms of motion blur.

Example 2

When using the 15 mm lens at 75 m AGL, the forward motion during a millisecond long exposure time at the nominal cruise speed of 23 m/s is 2.3 cm, which is more than 0.75 * the GSD of 2.4 cm, so we need to choose a faster shutter speed. Following the 0.75 * GSD at 23 m/s, 1/1600 will do.

To simplify the decision, the software shows the minimum allowable shutter speed in the camera preparation screen of the pre­flight checklist, based on the above rules and the flight plan.

Note: The software always suggests the safest shutter speed. For example, it states 1/4000 as the minimum for the 35 mm lens at 75 m AGL while 1/3200 would suffice in calm and clear weather. You can always use a slightly different setting, taking into account weather and flight line orientation relative to the wind.
